Voltage Rating: The 0.6kV rating is a critical electrical specification, representing the maximum phase-to-earth voltage the cable can safely withstand. This aligns with global low-voltage distribution norms, as most residential, rural, and light commercial networks operate within this voltage range—typically stepping down from higher transmission voltages (11kV or 33kV) to 0.6kV for end-user delivery. The cable’s design includes a safety margin to handle temporary voltage fluctuations, such as 10-15% spikes from equipment startups (e.g., air conditioners, motors) or minor lightning-induced surges, without insulation breakdown.
Current-Carrying Capacity: Each 70mm² AAC core contributes to the cable’s robust current-handling capability. Under standard operating conditions (ambient temperature of 30°C, free air installation, wind speed of 0.5m/s, and solar radiation of 1000W/m²), the 3X70mm² configuration can transmit a continuous current of 160-180A. This capacity is sufficient to power 30-40 average households (each consuming 1-5kW) or 5-8 small commercial units (e.g., convenience stores, offices with moderate power needs). For short-term overloads (up to 2 hours), the cable can handle up to 220A without overheating, thanks to the thermal stability of its Insulation Materials.
Dielectric Strength: The insulation (either XLPE or PVC) provides essential dielectric protection. XLPE insulation offers a dielectric strength of 20-25kV/mm, ensuring it resists electrical breakdown even in humid or dusty environments—critical for outdoor aerial installations. PVC Insulation, while slightly lower at 10-15kV/mm, still exceeds the requirements for 0.6kV operation, making it a cost-effective choice for less demanding settings. Both insulation types minimize leakage current (typically <10μA at 0.6kV), reducing energy loss and enhancing safety.
Insulation Resistance: Measured using a 500V megohmmeter at 20°C, the insulation resistance of XLPE-Insulated Cables exceeds 1000MΩ, while PVC-insulated variants reach 500-800MΩ. High insulation resistance prevents current leakage to the environment or between cores, further improving energy efficiency and reducing the risk of short circuits.
Conductor Tensile Strength: AAC Conductors have a minimum tensile strength of 80-100MPa, which is sufficient for aerial installations with moderate span lengths (40-80 meters between utility poles). While lower than alloyed Aluminum Conductors (e.g., AAAC at 120-140MPa), AAC’s strength is adequate for low-voltage applications where the cable’s self-weight (approximately 0.25kg/m for 3X70mm²) and wind loads are relatively low. This strength prevents excessive sagging, which could lead to contact with trees, buildings, or the ground.
Elongation at Break: AAC conductors exhibit an elongation at break of 15-20%, allowing them to stretch slightly under tension (e.g., during strong winds or ice accumulation) without breaking. This Flexibility absorbs mechanical stress, reducing the risk of conductor failure in dynamic outdoor conditions.
Insulation and Sheath Mechanical Properties: XLPE insulation has a Shore D hardness of 60-70, providing good resistance to abrasion and impact. LLDPE sheaths (commonly used for outdoor protection) have an impact strength of 5-10kJ/m² at -40°C, ensuring they withstand cold weather impacts from tree branches or maintenance tools. PVC Sheaths, while less flexible at low temperatures, offer a Shore D hardness of 70-80, making them durable in mild climates.
Bending Radius: The cable has a minimum bending radius of 10 times its outer diameter (OD) for fixed installations and 15 times its OD for dynamic bending (e.g., during installation). With an outer diameter of 20-25mm (depending on insulation and sheath thickness), the fixed bending radius ranges from 200-250mm—allowing easy routing around utility poles or obstacles without damaging internal components.
Conductor Cross-Sectional Area: Each of the 3 cores has a nominal cross-sectional area of 70mm², with a tolerance of ±5% (per IEC standards). The actual conductor diameter is approximately 9.4mm, and each core is composed of 19 Stranded Wires (2.1mm each) to enhance flexibility. The stranded design also improves current distribution across the conductor, reducing skin effect (a phenomenon that increases resistance at higher frequencies) for more efficient transmission.
Insulation Thickness: XLPE insulation has a minimum thickness of 1.0-1.2mm per core, while PVC insulation ranges from 1.2-1.5mm. This thickness is calibrated to balance electrical protection and cable compactness—thicker insulation would increase weight and cost, while thinner insulation risks breakdown.
Sheath Thickness: LLDPE or PVC sheaths have a minimum thickness of 1.8-2.0mm, providing a robust barrier against physical damage and environmental factors. The sheath’s uniform thickness (variation <0.2mm) ensures no weak points that could lead to premature failure.
Overall Cable Dimensions: The 3X70mm² ABC Cable has an outer diameter of 20-25mm and a weight of 0.25-0.30kg/m. This compact size reduces wind resistance (lowering the risk of cable oscillation during storms) and simplifies installation in tight spaces, such as between existing Power Lines on utility poles.
3-Core Bundled Design: Unlike traditional Overhead Cables that require separate phase and neutral conductors, this ABC variant integrates 3 cores into a single unit. This design simplifies installation by eliminating the need to string multiple wires, reducing labor time by 30-40% compared to conventional systems. It also minimizes the risk of phase-to-phase or phase-to-neutral faults, as the Insulated Cores are enclosed within a single sheath—preventing accidental contact between live conductors. Additionally, the bundled structure reduces visual clutter on utility poles, improving aesthetics in residential and suburban areas.
AAC Conductor: Cost-Effective and Lightweight: AAC is a standout feature, offering a balance of conductivity, weight, and cost. Pure aluminum’s conductivity (61% IACS) ensures efficient current transmission, while its low density (2.7g/cm³) reduces the cable’s overall weight. This lightweight property lowers the load on utility poles, allowing the use of smaller, more affordable poles (e.g., 8-10m wooden poles instead of 12m steel poles) and reducing installation costs. AAC is also 30-40% less expensive than Copper Conductors, making the cable a budget-friendly choice for large-scale projects like rural electrification.
Dual Insulation Options for Versatility: The availability of XLPE or PVC insulation allows customization for different environments. XLPE is ideal for harsh outdoor conditions—resisting moisture, UV radiation, and temperatures up to 90°C—making it suitable for rural, coastal, or industrial areas. PVC, with its lower cost and good performance in mild climates, is perfect for indoor aerial runs (e.g., in commercial buildings) or residential areas with moderate weather.
Weather-Resistant Sheathing: LLDPE sheaths (for outdoor use) are formulated with UV stabilizers and carbon black to resist sunlight degradation. Accelerated weathering tests show these sheaths retain 80% of their flexibility and impact strength after 10 years of outdoor exposure, extending the cable’s service life to 15-20 years. PVC sheaths, while less UV-resistant, work well in shaded or indoor settings, providing reliable mechanical protection at a lower cost.
Residential Subdivisions: In housing complexes or suburban neighborhoods, the 3X70mm² AAC ABC cable is strung along utility poles to supply power to individual homes. Its compact design reduces pole clutter, and its lightweight construction simplifies installation in areas with existing infrastructure. For example, a 50-home subdivision can be powered by a single run of this cable, eliminating the need for multiple separate conductors. The insulated and sheathed design also enhances safety for residents, especially children and pets, by preventing accidental contact with live wires.
Rural Electrification: Rural areas often lack access to reliable power due to long distances and limited budgets. This ABC cable addresses these challenges: AAC’s cost efficiency reduces material costs, and the bundled design cuts labor time. In remote villages, the cable can be installed over 40-80m spans between wooden poles, extending power to homes, schools, and small community centers. The weather-resistant sheath withstands rural hazards like strong winds, heavy rain, and dust, ensuring long-term reliability. For instance, in a village of 100 households, this cable can be deployed at a 30% lower cost than copper-based alternatives.
Light Commercial Spaces: Small commercial buildings—such as convenience stores, offices, and small workshops—have moderate power demands that align with the cable’s 0.6kV rating and 160-180A capacity. Aerial installation avoids the high costs of underground cabling (which can be 2-3 times more expensive) and allows quick deployment. For example, a strip mall with 5 stores can use this cable to supply power to lighting, HVAC systems, and point-of-sale equipment, with room for future expansion.
Agricultural Facilities: Farms, greenhouses, and small irrigation systems require reliable low-voltage power. The cable’s moisture resistance (from XLPE insulation and LLDPE sheath) protects against agricultural chemicals (e.g., fertilizers, pesticides) and humidity in greenhouses. Aerial installation keeps the cable out of the way of farm machinery (e.g., tractors, harvesters), reducing the risk of damage. For a 10-acre greenhouse, the cable can power irrigation pumps, heating systems, and lighting, ensuring consistent crop growth.
Conductivity: At 61% IACS, AAC offers sufficient conductivity for 0.6kV low-voltage transmission. While lower than copper (100% IACS), AAC’s conductivity is more than enough to handle the current loads of residential and light commercial applications. For the 70mm² core, this translates to low electrical resistance (approximately 0.27Ω/km at 20°C), minimizing energy loss.
Lightweight: With a density of 2.7g/cm³, AAC is 3.3 times lighter than copper. This reduces the cable’s weight per meter (0.25kg/m for 3X70mm²), lowering the load on utility poles. In practice, this means poles can be spaced 40-80 meters apart without additional reinforcement, reducing infrastructure costs.
Cost Efficiency: Aluminum is significantly less expensive than copper (approximately 1/5 the cost per ton), making AAC conductors 30-40% cheaper than Copper Conductors of the same cross-sectional area. For large projects (e.g., a 10km rural electrification line), this can result in savings of $50,000 or more.
Corrosion Resistance: Pure aluminum forms a thin, stable oxide layer (Al₂O₃) on its surface, protecting it from corrosion in most environments. While less resistant to saltwater than alloyed aluminum, AAC performs well in rural, suburban, and inland commercial areas—making it suitable for the cable’s target applications.
XLPE (Cross-Linked Polyethylene):
Thermal Stability: XLPE is a thermoset material created by cross-linking polyethylene molecules. It can operate at continuous temperatures up to 90°C and handle short-term overloads at 130°C—far exceeding PVC’s 70°C continuous limit. This makes it ideal for areas with high ambient temperatures (e.g., tropical regions) or applications with frequent overloads (e.g., commercial buildings with peak-hour equipment use).
Environmental Resistance: XLPE is highly resistant to moisture (water absorption <0.01% by weight), chemicals, and UV radiation. It does not degrade in humid or dusty conditions, ensuring long-term insulation performance. In outdoor tests, XLPE-Insulated Cables retained 90% of their dielectric strength after 15 years of exposure.
Longevity: With a service life of 20-25 years, XLPE insulation outlasts PVC (10-15 years), reducing the need for cable replacement and lowering lifecycle costs.
PVC (Polyvinyl Chloride):
Cost-Effectiveness: PVC is 20-30% cheaper than XLPE, making it a preferred choice for budget-constrained projects or indoor applications (e.g., commercial building ceilings) where environmental exposure is minimal.
Ease of Processing: PVC melts at lower temperatures (160-180°C) than XLPE, simplifying the extrusion process and reducing manufacturing costs.
Good Mechanical Protection: PVC has high abrasion resistance, making it suitable for areas with potential contact with non-sharp objects (e.g., indoor cable trays). However, it is less flexible at low temperatures (<0°C) and degrades under prolonged UV exposure, limiting its use to mild, sheltered environments.
LLDPE (Linear Low-Density Polyethylene):
Flexibility: LLDPE has a low modulus of elasticity (100-200MPa), remaining flexible even at -40°C. This allows the cable to be bent during installation (within the specified bending radius) without cracking, critical for routing around utility poles.
UV and Impact Resistance: Formulated with UV stabilizers (e.g., HALS) and carbon black, LLDPE sheaths resist sunlight degradation. Accelerated UV testing (1000W/m² for 1000 hours) shows they retain over 80% of their impact strength. The sheath’s impact resistance (5-10kJ/m² at -40°C) protects against tree branches, wildlife, and maintenance tools.
Moisture Resistance: LLDPE is impermeable to water, preventing moisture ingress that could damage the insulation or conductors. This is essential for outdoor aerial installations exposed to rain, snow, or dew.
PVC Sheathing:
Cost and Availability: PVC sheaths are widely available and 15-25% cheaper than LLDPE, making them suitable for indoor or sheltered outdoor applications (e.g., under building eaves).
Chemical Resistance: PVC resists mild chemicals (e.g., cleaning agents in commercial buildings), but it is prone to degradation in strong acids or bases—limiting its use in industrial areas.
Fire Retardancy: PVC is inherently fire-retardant, releasing less smoke and toxic gases than some other polymers. This makes it a safe choice for indoor installations where fire safety is a priority.
Ingot Melting and Casting: Pure aluminum ingots (99.5% purity) are melted in a furnace at 660°C. Trace elements (iron, silicon) are added to enhance mechanical properties, and the molten aluminum is cast into cylindrical billets (120mm diameter, 3m length).
Extrusion to Rods: Billets are heated to 500°C and extruded into aluminum rods (9.5-12mm diameter) using a hydraulic extruder. This process shapes the aluminum into a uniform rod ready for drawing.
Cold Drawing: The rods are pulled through a series of diamond dies (with decreasing hole sizes) at room temperature, a process called cold drawing. This reduces the rod diameter to 2.1mm (the size of individual strands in the 70mm² core) while increasing tensile strength through work hardening. Each rod undergoes 5-7 drawing passes, with intermediate annealing (heating to 300-350°C for 1 hour) to relieve internal stress and maintain ductility.
Material Preparation: For XLPE insulation, pellets mixed with a peroxide cross-linking agent (e.g., dicumyl peroxide) are dried at 80°C for 2 hours to remove moisture (which can cause bubbles in the insulation). PVC insulation pellets are mixed with plasticizers (e.g., phthalates) and stabilizers (to prevent degradation during extrusion) and fed directly into the extruder without pre-drying.
Extrusion: The insulation material is fed into a single-screw extruder (with a length-to-diameter ratio of 25:1). For XLPE, the extruder temperature is set to 120-140°C (to melt the polymer without activating cross-linking); for PVC, it is 160-180°C. The molten insulation is forced through a cross-head die (custom-shaped to fit the 9.4mm AAC core) to apply a uniform layer. The die is calibrated to ensure insulation thickness: 1.0-1.2mm for XLPE and 1.2-1.5mm for PVC.
Cooling and Curing (for XLPE): Insulated cores pass through a water cooling tank (20-25°C) to solidify the insulation. XLPE-insulated cores then enter a curing tube (180-200°C) for 5-10 minutes, where the peroxide decomposes to cross-link polyethylene molecules—transforming XLPE into a thermoset material. PVC-insulated cores skip curing and proceed directly to quality checks after cooling.
Inspection: Each insulated core is inspected using a laser thickness gauge to verify insulation uniformity (tolerance ±0.1mm). A visual inspection checks for surface defects like bubbles, scratches, or uneven thickness; defective cores are rejected and recycled.
Core Bundling: Using a cabling machine, the three insulated cores are twisted together in a helical pattern (lay length 20-25 times the bundled core diameter, ~20mm) to create a compact 3-core assembly. This twisting enhances cable flexibility and prevents core separation during installation. The machine operates at 40-50 meters per minute, and the bundled assembly is tension-controlled to avoid stretching or damaging the insulation.
Sheath Extrusion: The bundled cores are fed into a second extruder for sheath application. For LLDPE sheaths, pellets mixed with UV stabilizers (0.1-0.5% by weight) and carbon black (2-3% for UV protection) are used; PVC sheath pellets include fire retardants and stabilizers. The extruder temperature is 160-180°C for LLDPE and 170-190°C for PVC. A cross-head die (matching the 20-25mm bundled diameter) applies a 1.8-2.0mm thick sheath, and the cable passes through a water cooling tank to solidify the sheath.
Marking: A laser printer applies permanent markings to the sheath at 1-meter intervals, including the cable specification (3X70mm² AAC ABC, 0.6kV), insulation/sheath material (e.g., “XLPE/LLDPE”), manufacturer name, and production date. This ensures traceability and compliance with standards.
Electrical Tests:
Voltage Withstand Test: The cable is submerged in water at 20°C and subjected to a 3kV AC voltage for 5 minutes (phase-to-sheath). No breakdown or leakage current (>10μA) is allowed.
Insulation Resistance Test: A 500V megohmmeter measures resistance between cores and core-to-sheath. XLPE-insulated cables must exceed 1000MΩ; PVC-insulated cables, 500MΩ.
Current-Carrying Capacity Test: A sample is heated to 90°C (XLPE) or 70°C (PVC) and loaded with current until temperature stabilizes. The measured current must be ≥160A.
Mechanical Tests:

Impact Test: The sheath is tested via Izod method at -40°C (LLDPE) or 23°C (PVC). Impact strength must be ≥5kJ/m² (LLDPE) or ≥3kJ/m² (PVC).
Bending Test: The cable is bent around a mandrel (10x OD for fixed installation) 10 times, then inspected for insulation/sheath cracks—none are allowed.
Dimensional Tests:
Conductor Area: A core cross-section is measured via microscope; area must be 70mm² ±5%.
Insulation/Sheath Thickness: A laser gauge checks 10 points per meter; minimum thicknesses (1.0mm XLPE, 1.8mm sheath) must be met.
Environmental Tests:
UV Resistance (LLDPE Sheath): A sample is exposed to 1000W/m² UV radiation for 1000 hours. After testing, impact strength must retain ≥80% of original value.
Moisture Resistance: The cable is submerged in 80°C water for 168 hours, then insulation resistance is measured—must remain ≥50% of initial value.
Wooden Spools: Made from heat-treated pine (compliant with ISPM 15 for international shipping) with a flange diameter of 800-1200mm and core diameter of 300-400mm. They can hold 500-1000 meters of 3X70mm² Cable (weight 125-300kg). The spool core is lined with corrugated cardboard to prevent sheath scratches, and the cable is wound in a tight, uniform pattern to avoid tangling.
Steel Spools: Galvanized steel spools (for heavy-duty use or long-term storage) have a flange diameter of 1000-1500mm and can hold 1000-2000 meters of cable (weight 250-600kg). They are rust-resistant and ideal for ocean shipping or repeated use.
Stretch Film: A 20-30μm thick polyethylene stretch film is wrapped around the spooled cable to seal out dust and moisture. The film is applied in a crisscross pattern with 50% overlap, ensuring full coverage.
Polyethylene (PE) Bag: For outdoor storage or humid environments, a 50-70μm thick PE bag is slipped over the stretch-wrapped spool and heat-sealed. A 50g desiccant packet is placed inside to absorb residual moisture, preventing insulation degradation.
Loading: 4-6 wooden spools (500m each) or 2-3 steel spools (1000m each) fit on one pallet, with a total weight of 500-1800kg. Spools are spaced evenly to distribute weight and prevent tipping.
Securement: Steel strapping (16mm wide, 0.8mm thick) is tightened around the spools and pallet in a crisscross pattern (tension 600-800N) to prevent movement. Edge protectors (cardboard or plastic) are placed between the strapping and spool flanges to avoid damage.

Environmental damage from natural disasters (e.g., lightning strikes, floods, tornadoes) or extreme conditions beyond the cable’s design limits (e.g., temperatures < -40°C for LLDPE sheaths).
Normal wear and tear (e.g., minor sheath scratches that do not affect insulation).
Claim Notification: The customer contacts our after-sales team within 30 days of discovering the defect, providing:
Order number, delivery date, and cable batch number
Detailed description of the defect (e.g., “LLDPE sheath cracked after 2 years of outdoor use”)
Photos/videos of the defect (showing the location, extent of damage, and surrounding environment)
Installation and maintenance records (to demonstrate proper use)
Claim Review: Our team reviews the claim within 3 working days. We may request additional information (e.g., an independent test report from a certified lab) if the defect’s cause is unclear.
Inspection: If needed, we send an engineer to the customer’s site to inspect the defective cable—typically within 5-7 working days for domestic claims and 10-14 days for international claims. The engineer assesses the defect, verifies installation practices, and prepares an inspection report.
Claim Approval: If the defect is covered under warranty, we approve the claim within 2 working days of receiving the inspection report. We offer three resolution options:
Replacement: We provide a new cable of the same specifications, free of charge, including shipping costs. The defective cable must be returned to us (at our expense) for analysis.
Repair: For minor defects (e.g., small sheath tears), we send repair materials (e.g., LLDPE repair tape, heat shrink tubing) and provide step-by-step repair guidance.
Refund: If the defect cannot be resolved by replacement or repair (e.g., widespread insulation failure), we issue a full refund of the purchase price for the defective portion of the cable.
Follow-Up: After resolving the claim, we follow up with the customer 1 month later to ensure satisfaction and address any remaining concerns. We also use the defect analysis to improve our production process—for example, if multiple claims involve sheath UV degradation, we increase the UV stabilizer content in LLDPE pellets.
Maintenance Manual: Each order includes a maintenance manual outlining recommended activities:
Visual Inspections: Conduct every 6 months to check for:
Sheath damage (scratches, cracks, UV discoloration)
Conductor sagging (exceeding 10% of the span length)
Clamp loosening or corrosion
Vegetation growth near the cable (trim trees within 1 meter of the cable to prevent damage)
Electrical Testing: Conduct every 2 years to:
Measure insulation resistance (should remain ≥500MΩ for PVC, ≥1000MΩ for XLPE)
Check for leakage current (should be <10μA at 0.6kV)
Verify current-carrying capacity (using a clamp meter to ensure it does not exceed 180A)
Cleaning: Clean the cable every 12 months to remove dust, dirt, or agricultural residues (e.g., fertilizer) using a soft brush and mild detergent. Avoid high-pressure water, which can damage the sheath.
Maintenance Training: We offer training sessions for customer maintenance teams—either on-site or via video call. Training covers:
How to use testing equipment (megohmmeters, clamp meters)
How to identify early signs of cable degradation (e.g., brittle sheath, reduced insulation resistance)
How to perform minor repairs (e.g., patching sheath tears)
Annual Maintenance Check: For large customers (e.g., utilities with >50,000 meters of cable installed), we offer an annual maintenance check:
Our engineers visit the customer’s site to inspect a sample of the cable (10% of installed length)
Conduct electrical and mechanical tests
Prepare a maintenance report with:
Current cable condition
Recommendations for repairs or replacements (e.g., “Replace 500 meters of cable with UV-damaged sheath”)
A customized maintenance schedule for the next year
Post-Delivery Surveys: Sent to customers 1 month after delivery, covering satisfaction with:
Product quality (conductor, insulation, sheath)
Shipping and delivery (timeliness, packaging)
Sample and after-sales support
Annual Reviews: For long-term customers, we conduct annual review meetings (in-person or virtual) to discuss:
Performance of cables installed over the past year
Challenges faced (e.g., installation delays, warranty claims)
Future needs (e.g., Custom Cable specifications, bulk order discounts)
Online Portal Feedback: Customers can submit feedback, questions, or complaints via our portal at any time—with a response guaranteed within 24 hours.
If multiple customers report slow sample delivery, we optimize the sample production process to reduce lead time from 3 days to 1 day.
If feedback highlights confusion about the installation manual, we revise the manual to include more diagrams and step-by-step videos.
If warranty claims involve AAC conductor corrosion in coastal areas, we develop a new AAC alloy with added zinc (for enhanced corrosion resistance) and launch it as an optional upgrade.
