China Flexible, bend‑resistant plastic‑coated copper stranded wire, fully customizable in all parameters Manufacturer, Supplier

Plastic-coated copper stranded wire features a high-purity copper strand core for conductivity, encased in a uniform plastic sheath (PVC/PE/nylon/PTFE, etc.). It retains the strand’s excellent conductivity and flexibility while adding wear, corrosion, water resistance and insulation via the sheath. Available in customized cross-section, wire diameter, sheath material and thickness, it is ideal for power wiring, rail transport, automation equipment and harsh outdoor grounding/connections — a perfect blend of electrical performance and durable protection.

Product Description

Cross-sectional area, wire diameter, sheath thickness, color and length can be tailored to customer drawings or requirements.

Applications

Plastic-coated copper stranded wire is widely used for indoor and outdoor wiring in power and distribution systems, grounding and connections in harsh environments such as rail transport, ships and mines, flexible cable assemblies for automation equipment and robotics, signal transmission and shielded links in communication and security systems, and waterproof power supply cables for outdoor and landscape lighting.

Structure

  • Copper Strand Core: Made of high-purity soft copper wires (≥99.9%) precisely stranded at specified lays and strand counts to ensure excellent conductivity and mechanical strength.
  • Plastic Sheath: An extruded or applied plastic layer of selected material on the outside of the strand; available in various colors, hardness levels, temperature resistance and chemical resistance grades.
  • Optional Additional Layers: Such as flame-retardant, shielding or waterproof sealing layers for enhanced protection in demanding conditions.
  • Frequently Asked Questions
    1. What materials are available for the plastic sheath?
    We provide several options including PVC for cost-efficiency, PE for low-temperature resistance, Nylon for high abrasion resistance, and PTFE for superior chemical and heat resistance.
    2. Can I customize the wire dimensions and color?
    Yes, the product is fully customizable. We can adjust the cross-sectional area, wire diameter, sheath thickness, color, and length based on your specific technical drawings or project needs.
    3. Is this copper stranded wire suitable for outdoor use?
    Absolutely. With specific sheath materials like PE or waterproof layers, it is ideal for outdoor wiring, landscape lighting, and harsh environments like mines and ships.
    4. What is the purity level of the copper used in the core?
    The core is manufactured using high-purity soft copper wires with a purity of ≥99.9%, ensuring maximum conductivity and flexibility.
    5. What makes this wire flexible and bend-resistant?
