Custom Cut & Weld Solutions for Flexible Copper Strand Connectors

A flexible copper stranded connection is a highly conductive and flexible component made by precision-twisting high-purity copper wires (typically T1/T2 red copper, ≥99.9% purity) into circular or rectangular shapes. It features excellent flexibility, bend resistance, and reliable conductivity, ideal for dynamic, confined, or vibration-prone applications. It can be precisely cut and welded to terminals, busbars, or other conductive parts, ensuring secure, low-resistance, and durable connections while retaining flexibility and mechanical strength.

    Structural Composition

    Conductor:​ High-purity electrolytic copper wire (T1/T2 red copper, ≥99.9% purity). 
    Structure:​ Precision-twisted multi-strand fine copper wires (0.05–0.3 mm), forming circular, rectangular, or custom cross-sections. Compact, flexible, and highly tensile. 
    Surface Treatment (Optional):​ Bare, tin-plated, or silver-plated for enhanced oxidation resistance, corrosion resistance, and weldability. 
    Protection (Optional):​ PVC/silicone insulation or metal shielding for insulation, EMI resistance, or high-temp performance. 

    Applications 

    Power systems, rail traction, automation/robotics, welding/electrolysis equipment, marine engineering, new energy (PV/wind), and building/construction (slip rings, lighting). 

    Key Features

    High Flexibility:​ Twisted structure enables tight bending and vibration resistance. 
    Excellent Conductivity:​ Low resistance for stable high-current/signaling. 
    Mechanical Strength:​ Withstands tension, compression, and fatigue. 
    Fatigue Resistance:​ Reliable under repeated motion. 
    Customizable:​ Adjustable cross-section, length, shape, and surface finish. 
    Protective Options:​ Insulation, shielding, and high-temp materials available.
