1. Product-Specific Details

1.1 Specifications and Parameters

The Single Core flexible RV round copper Ground Wire, designed as an Earth Cable with PVC Insulation and a distinctive yellow-green color, is available in sizes ranging from 6 to 95 sq mm. These specifications are engineered to meet strict safety and performance standards for grounding applications across various industries.

Conductor Size and Current-Carrying Capacity: The cross-sectional areas (6, 10, 16, 25, 35, 50, 70, 95 sq mm) directly determine the cable’s current-handling capability. For example, the 6 sq mm conductor can carry up to 32A under normal operating conditions (ambient temperature 30°C), while the 95 sq mm variant supports a maximum of 185A. These values are derived from IEC 60228 standards, ensuring compatibility with low-voltage electrical systems (typically 0.6/1kV).

Insulation Properties: The PVC insulation has a thickness ranging from 0.8mm (for 6 sq mm) to 1.8mm (for 95 sq mm), providing electrical isolation with a dielectric strength of ≥15kV/mm. This insulation is rated for continuous operating temperatures between -15°C and 70°C, making it suitable for both indoor and outdoor environments. It also exhibits resistance to moisture, oils, and general chemicals, preventing degradation in harsh conditions.

Mechanical Parameters: The cable’s Flexibility is enhanced by its stranded Copper Conductor, composed of multiple fine Copper Wires (0.2mm diameter each) twisted together. This design allows a minimum bending radius of 4 times the cable’s outer diameter (OD) for fixed installations and 8 times the OD for dynamic applications (e.g., equipment with moving parts). The outer diameter varies with size: 6 sq mm has an OD of ~5.2mm, while 95 sq mm measures ~14.8mm. The weight per meter ranges from 0.07kg (6 sq mm) to 0.85kg (95 sq mm), facilitating easy handling during installation.

Color Coding: The yellow-green insulation is mandated by international standards (e.g., IEC 60446) to clearly identify the cable as a grounding conductor, preventing confusion with phase or neutral wires in electrical systems.

1.2 Special Purpose

This RV ground wire is specifically designed for electrical grounding, serving as a critical safety component in diverting fault currents to the earth, thereby protecting equipment and personnel from electric shock. Its applications span multiple sectors:

Residential and Commercial Buildings: In homes, offices, and malls, it connects electrical panels, appliances (e.g., refrigerators, air conditioners), and metal fixtures (e.g., water pipes, structural steel) to the earth electrode. The 6-25 sq mm sizes are commonly used here, as they handle typical fault currents from household circuits.

Industrial Facilities: Factories and manufacturing plants utilize larger sizes (35-95 sq mm) to ground heavy machinery, transformers, and control systems. For example, in automotive plants, it ensures welding robots and assembly lines are grounded to prevent static discharge or equipment damage during fault conditions.

Renewable Energy Systems: Solar farms and wind turbines rely on these cables to ground inverters, mounting structures, and lightning protection systems. The flexibility of the Stranded Conductor allows easy routing in tight spaces, such as between solar panels or within turbine nacelles.

Marine and Automotive Applications: In boats and vehicles, the cable grounds metal components (e.g., hulls, chassis) to dissipate static electricity and protect against electrical faults. The PVC insulation’s resistance to water and vibration makes it ideal for these dynamic environments.

1.3 Materials and Styles

Conductor Material: High-purity electrolytic copper (99.95% purity) is used for the conductor, ensuring excellent conductivity (≥58 MS/m) and corrosion resistance. The stranded design (class 5 flexibility per IEC 60228) enhances durability and ease of bending, critical for installations in confined spaces.

Insulation Material: The PVC insulation is a flame-retardant compound (UL94 V-0 rated), minimizing fire spread in case of overheating. It is formulated to resist UV radiation, ensuring longevity in outdoor applications without cracking or brittleness.

Style Variations: The cable is available in a single core, round configuration, with the yellow-green color as standard. Custom lengths (from 1m to 500m) can be ordered, and some variants include a tinned copper conductor for enhanced corrosion resistance in high-moisture environments (e.g., coastal areas or chemical plants).

1.4 Production Process

The manufacturing process adheres to strict quality controls to ensure consistency and safety:

Copper Stranding: High-purity copper rods are drawn into fine wires (0.2mm diameter) using diamond dies. These wires are then stranded together in a helical pattern using a high-speed stranding machine, with the number of wires varying by size (e.g., 6 sq mm uses 19 wires, while 95 sq mm uses 127 wires).

Insulation Extrusion: The stranded conductor is fed into an extrusion line where molten PVC (at 160-180°C) is applied uniformly around it. The extrusion die is calibrated to achieve the precise insulation thickness for each cable size. A color masterbatch is added to the PVC compound to achieve the yellow-green color, ensuring uniformity across batches.

Cooling and Curing: The Insulated Cable passes through a water bath to cool and solidify the PVC. This step is critical to maintaining insulation integrity and dimensional stability.

Quality Testing: Each batch undergoes rigorous testing, including:

Insulation resistance (≥1000 MΩ at 500V DC).

Voltage withstand test (3kV AC for 5 minutes without breakdown).

Tensile strength and elongation of insulation (≥12MPa and ≥150%, respectively).

Conductor resistance (compliant with IEC 60228 class 5).

Spooling: Approved cables are spooled onto plastic or wooden reels, with lengths marked clearly for customer reference.

2. General Product Information

2.1 Packaging

The RV ground wires are packaged to protect against damage during storage and transportation:

Small Lengths (1-50m): Supplied in sealed plastic bags or cardboard boxes, with labels indicating size, length, batch number, and compliance (e.g., CE, UL).

Large Lengths (100-500m): Spooled onto lightweight plastic reels (for 6-25 sq mm) or wooden reels (for 35-95 sq mm) to support heavier weights. Reels are fitted with steel flanges to prevent cable slippage and wrapped in moisture-resistant plastic film.

Export Packaging: For international shipments, reels are crated in ISPM 15-compliant wooden boxes to meet phytosanitary requirements, with additional padding to avoid abrasion during transit.

2.2 Transportation

Transportation is tailored to the cable’s size and destination:

Domestic Shipping: Cables are transported via road using curtain-sided trucks. Reels are secured with steel straps and wooden blocks to prevent movement. For small orders, courier services (e.g., DHL, FedEx) are used, with cables packed in rigid tubes.

International Shipping: Large consignments are shipped via sea in 20ft or 40ft containers. Reels are stacked vertically (small sizes) or horizontally (large sizes) and secured with dunnage bags to minimize shifting. Temperature-controlled containers are used for shipments to extreme climates to prevent PVC degradation.

Handling Guidelines: Cables must be loaded/unloaded using forklifts or cranes with appropriate slings to avoid bending beyond the minimum radius. Exposure to direct sunlight for extended periods is avoided to prevent UV damage.

2.3 Delivery
