600V High-Temp 105°C Flame Retardant Wire - Stranded Pure Copper for Industrial Use: Full Product Guide

1. Product-Specific Details: Core Performance, Materials, and Craftsmanship

1.1 Core Electrical & Thermal Specifications

This Industrial Wire is purpose-built to address the unique challenges of high-temperature industrial settings, with its core parameters refined to prioritize stability, safety, and long-term functionality. Its defining electrical specification is a rated voltage of 600V, which classifies it as a low-voltage industrial wire—a category that aligns with the power supply needs of the vast majority of industrial equipment. This voltage rating is not arbitrary: it is calibrated to deliver consistent power without electrical breakdown under standard low-voltage operational loads, avoiding the inefficiencies of underrated wires or the unnecessary complexity of higher-voltage alternatives.


A cornerstone of its performance is 105°C continuous high-temperature resistance, a capability validated through rigorous professional testing protocols. In sustained 105°C environments, the wire’s insulation layer and conductor maintain uncompromised structural and functional integrity: the insulation does not soften, crack, peel, or undergo premature aging (a common failure point for Standard Wires), and the conductor exhibits no abnormal increase in electrical resistance. This stability is critical for preventing power transmission failures, as resistance spikes or insulation degradation can lead to overheating, short circuits, or equipment shutdowns. Beyond continuous operation, the wire also tolerates short-term instantaneous high temperatures of up to 120°C—a thermal margin that far exceeds the 60-70°C upper limit of ordinary industrial wires. This extended thermal range ensures reliability even in settings where temperature fluctuations or occasional heat surges are unavoidable, reducing maintenance frequency and downtime.

1.2 Conductor: High-Purity Material & Stranded Structural Design

The conductor is the "backbone" of the wire’s electrical performance, and its design is optimized for conductivity, Flexibility, and durability. It is constructed from stranded pure copper with a minimum purity of 99.95%—a material choice selected for its superior electrical conductivity compared to alternatives like copper alloys (which contain impurities that hinder current flow) or tinned copper (where the tin layer can degrade in high temperatures). This high purity translates to measurable performance: the conductor’s DC resistance (at 20°C) is ≤10.1Ω/km, a low value that minimizes power loss during transmission. In high-temperature environments, where conductor heating can exacerbate line burden and reduce efficiency, this low resistance is particularly valuable—it prevents excessive heat buildup in the conductor, ensuring consistent power delivery to connected equipment and lowering the risk of overheating-related failures.


The stranded structure of the conductor is another critical design feature, engineered for flexibility and adaptability in complex industrial installations. Each individual Copper Strand within the conductor has a diameter of just 0.1-0.2mm—thin enough to enhance flexibility but thick enough to maintain mechanical strength. These strands are assembled using a precision stranding process that controls stranding pitch (the distance between consecutive twists) and tension to ensure uniform distribution and tight bonding. This process eliminates gaps between strands (which could trap air or moisture and degrade performance over time) and creates a conductor with a minimum bending radius of 3-5 times the wire’s outer diameter. This flexibility allows the wire to be routed through narrow spaces, around equipment corners, and in confined areas where rigid solid conductors would be difficult or impossible to install. Additionally, the stranded structure enhances the wire’s ability to withstand slight vibrations and displacements common in industrial operations—unlike solid conductors, which can fracture under repeated movement—extending the wire’s service life.

1.3 Insulation Layer: Material Options & Performance Enhancements

The insulation layer is a critical barrier that protects the conductor, enhances high-temperature resistance, and contributes to flame retardancy. Two primary Insulation Materials are offered, each tailored to different industrial needs:

1.3.1 Flame-Retardant PVC Insulation (Regular Models)

Regular models use flame-retardant polyvinyl chloride (PVC) insulation, formulated with specialized additives to boost performance in industrial environments. This PVC compound offers three key benefits:


  • High-Temperature Stability: It maintains structural integrity at 105°C, resisting softening or degradation during continuous high-temperature operation—unlike standard PVC, which may become brittle or lose insulating properties above 70°C.

  • Chemical & Oil Resistance: It forms a protective barrier against oil pollution and slight chemical solvent erosion, common in industrial settings such as manufacturing plants or mechanical workshops. This resistance prevents insulation degradation that could expose the conductor to short circuits.

  • Flame-Retardant Synergy: It works in tandem with the wire’s flame-retardant system (detailed in Section 1.4) to suppress fire spread, ensuring compliance with safety standards.

1.3.2 Cross-Linked Polyethylene (XLPE) Insulation (High-End Models)

High-end models use cross-linked polyethylene (XLPE) insulation, produced through a cross-linking process that creates a more robust molecular structure. This material delivers superior performance for demanding applications:


  • Enhanced High-Temperature Resistance: It tolerates continuous 105°C operation with even greater stability than flame-retardant PVC, and can withstand short-term temperatures above 120°C without degradation.

  • Aging & Mechanical Strength: The cross-linked molecular structure makes XLPE highly resistant to aging, UV radiation, and mechanical stress (such as impact or abrasion). This extends the wire’s service life to over 10 years—a significant advantage for long-term industrial equipment like continuously operating production lines or large industrial furnaces.

  • Superior Dielectric Strength: XLPE has a higher dielectric strength than PVC, reducing the risk of electrical breakdown even in humid or dusty environments, and enhancing overall electrical safety.

1.4 Flame-Retardant Performance & Compliance

Flame retardancy is non-negotiable for industrial wires, especially in high-temperature settings where fire risks are elevated. This wire meets strict global and national standards, ensuring maximum safety:


  • Compliance with GB/T 19666-2019: Regular models meet the Class B flame-retardant requirements of China’s national standard GB/T 19666-2019 (General Specification for Flame-Retardant and Fire-Resistant Wires, Cables or Optical Cables), while high-end models exceed this to meet Class A flame-retardant standards—the highest level for flame retardancy in this specification.

  • Flame-Suppression Mechanism: The insulation layer (whether PVC or XLPE) is infused with environmentally friendly flame retardants (free of halogens and heavy metals, aligning with global environmental regulations). When exposed to an open flame, these retardants trigger a chemical reaction that forms a dense, heat-resistant carbonized layer on the insulation surface. This layer acts as a barrier, inhibiting flame spread along the wire and blocking the release of flammable gases that fuel fires.

  • Low Smoke & Toxicity: The flame-retardant formulation minimizes smoke production and reduces the release of toxic gases (such as chlorine or carbon monoxide) during combustion—critical for protecting personnel and equipment in enclosed industrial spaces.

  • Self-Extinguishing Capability: A key performance metric is the wire’s ability to self-extinguish within 30 seconds of removing the fire source, limiting fire damage and preventing the spread of flames to surrounding equipment.

1.5 Production Craftsmanship & Quality Control

The wire’s performance is ensured by rigorous manufacturing processes and strict quality control (QC) protocols, implemented at every stage of production:

1.5.1 Precision Manufacturing Processes

  1. Copper Strand Drawing: Pure copper rods are drawn into thin strands (0.1-0.2mm diameter) using specialized wire-drawing machines, which ensure uniform diameter and a smooth surface finish (imperfections in strand diameter can reduce conductivity or cause insulation gaps).

  2. Strand Assembly: Strands are stranded using computer-controlled precision stranding machines, which adjust pitch and tension to ensure even distribution and tight bonding. This process is monitored in real time to avoid inconsistencies.

  3. Insulation Extrusion: For PVC insulation, the flame-retardant PVC compound is heated and extruded over the Stranded Conductor using an extrusion machine with precise temperature control—ensuring a uniform insulation thickness (critical for electrical safety and thermal resistance). For XLPE insulation, the extruded layer undergoes a cross-linking process (either chemical or radiation-based) to create the robust molecular structure.

  4. Post-Production Curing: Insulated Wires are cured in temperature-controlled ovens to stabilize the insulation material, enhancing its thermal and mechanical properties.

1.5.2 Strict Quality Control Testing

QC testing is integrated into every production stage, with samples tested at multiple checkpoints:


  • Conductor Conductivity Testing: Each batch of Stranded Conductors is tested for DC resistance, ensuring compliance with the ≤10.1Ω/km standard.

  • Thermal Resistance Testing: Samples are exposed to 105°C continuous heat (and 120°C short-term heat) for extended periods, with insulation and conductor performance monitored for degradation.

  • Flame-Retardant Testing: Samples are tested in accordance with GB/T 19666-2019, measuring flame spread distance, self-extinguishing time, and smoke/toxic gas emission.

  • Mechanical Testing: Bending tests validate the minimum bending radius, while tensile and abrasion tests assess insulation durability.

  • Chemical Resistance Testing: PVC-insulated samples are exposed to industrial oils and solvents to check for insulation degradation.


Only wires that pass all tests are approved for packaging and shipment, ensuring consistent performance across every meter.

1.6 Product Dimensions & Customization

While core specifications (600V Rated voltage, 105°C resistance, stranded Pure Copper Conductor) are standardized, the wire is available in a range of dimensions to meet diverse industrial needs:


  • Conductor Cross-Sectional Areas: Common options include 0.5mm², 0.75mm², 1mm², 1.5mm², 2.5mm², 4mm², and 6mm²—covering power requirements from small control circuits to medium-sized auxiliary equipment.

  • Outer Diameter: Varies with conductor size and insulation thickness, typically ranging from 2.0mm to 8.0mm, ensuring compatibility with Standard Cable glands, conduits, and installation spaces.


Customization options are also available to address unique customer requirements:


  • Custom conductor cross-sectional areas for non-standard power needs.

  • Specialized insulation colors (beyond standard black, red, blue, yellow) for color-coding in complex wiring systems (e.g., differentiating control circuits from power circuits).

  • Custom lengths (beyond standard spool sizes of 100m, 200m, 500m) to reduce waste and simplify installation.

  • Enhanced formulations (e.g., extra chemical resistance for corrosive environments, or reinforced insulation for high-vibration settings).

2. General Product Information: Packaging, Transportation, Ordering, and After-Sales

2.1 Packaging Design & Protection

Packaging is engineered to protect the wire during storage, transportation, and on-site handling, while ensuring ease of use for installation teams:

2.1.1 Primary Packaging (Spools)

Spools are available in standard sizes corresponding to common lengths: 100m, 200m, and 500m. Each spool features a central core (for easy mounting on wire dispensers) and flanges to prevent the wire from slipping off during unspooling.

2.1.2 Secondary Packaging (Moisture & Dust Protection)

Each spool is wrapped in a thick, moisture-resistant plastic film to shield the wire from humidity, dust, and minor physical damage. This film is critical for wires stored in outdoor or semi-outdoor warehouses, where moisture can degrade insulation over time. For high-end XLPE-insulated models, an additional layer of anti-static film is added to prevent electrostatic damage to the insulation.

2.1.3 Bulk Packaging (Cartons)

For bulk orders (multiple spools of the same type), spools are packed into double-walled corrugated cardboard cartons with foam inserts or kraft paper padding to prevent movement and collision during transit. Each carton is labeled with a clear shipping mark containing: product model, conductor size, insulation type, length, flame-retardant class, manufacturing date, batch number, and safety warnings (e.g., “Keep Away from Open Flames,” “Store in Dry Environment”).
