Highly Flexible Stranded Copper Wire for Electricians
Product Features
Exceptional Flexibility: The multi-strand fine copper wire construction allows for easy bending, twisting, and routing, making it ideal for installations in confined spaces or with complex cable paths.
•Superior Conductivity: Manufactured from high-purity electrolytic copper (typically ≥99.9%) and annealed, it ensures low resistance and high-efficiency current transmission, complying with international conductor standards.
•High Fatigue Resistance & Durability: The stranded design distributes mechanical stress, offering a longer service life and higher reliability than solid-core wires in applications involving frequent flexing, vibration, or movement.
•Easy & Reliable Installation: Its inherent flexibility simplifies manual handling and crimping. The multiple fine strands compact to form a tighter connection with greater contact area under terminals, reducing the risk of hot spots and loosening.
•Effective Heat Dissipation: The micro-gaps between strands facilitate airflow, aiding in heat dissipation during operation.
Application Fields
This flexible stranded copper wire is widely used in demanding scenarios requiring reliable connectivity under physical stress. Key applications include complex wiring within distribution cabinets, equipment terminal connections, grounding system jumpers, power supply for mobile equipment, and interconnections in new energy systems. It is particularly suited for high-demand installations where space is limited, or where vibration and frequent flexing are present.
Structural Composition
Conductor:
Material: High-purity electrolytic copper (Cu ≥ 99.9%).
Temper: Annealed (softened), which is the key process for achieving flexibility by converting the copper from a hard-drawn to a soft state.
Construction: Comprised of multiple (from dozens to thousands) round copper wires, with individual wire diameters ranging from 0.05mm to 0.2mm. These wires are spirally stranded together, typically in a concentric lay pattern. Finer individual wires and a greater strand count result in a more flexible cable.
Optional Coatings:
Bare Copper: The most common and cost-effective option.
Tinned Copper: Features a tin layer over the copper wires, primarily providing anti-oxidation and corrosion resistance, improving solderability, and preventing adverse reactions between copper and certain insulation types.
Silver-Plated Copper: Used for specific applications requiring very high frequency performance or lower contact resistance. It offers superior performance at a higher cost.
Insulation (for insulated wires):
Materials: PVC (Polyvinyl Chloride), XLPE (Cross-Linked Polyethylene), Rubber (e.g., Silicone, EPR), Fluoropolymers, etc.
Function: Provides electrical insulation and basic mechanical protection. The material determines the cable's temperature rating and resistance to oil, chemicals, and environmental conditions.
