Twisted Copper Wire
Products Description
Twisted Copper Wire flexible busbars are formed by precision twisting and braiding of multiple strands of high-purity copper wire, and then manufactured with conductive terminals at both ends through pressure welding, stamping, or electroplating.
The product combines flexibility and high current-carrying capacity in its structure, capable of withstanding thermal expansion, vibration, and mechanical stress in electrical systems, while also allowing for flexible multi-angle wiring within limited space.
These Round Stranded Flexible Cords are widely used in new energy battery modules, high and low voltage switchgear, energy storage systems, rail transit traction equipment, and photovoltaic inverter systems.
It is not merely a connector, but a critical component ensuring safety and reliability in electrical systems.
Material Advantages
High Conductivity of Oxygen-Free Copper Wire
Using high-purity oxygen-free copper wire conforming to ASTM B170 standards, with a conductivity of ≥101% IACS, it effectively reduces power transmission loss and temperature rise compared to ordinary Round Braided Flexible Cords.
Coating Process Protection Technology
Tin-plated copper wire: Excellent oxidation resistance, suitable for long-term exposure or high-humidity environments;
Nickel-plated copper wire: Stronger stability at high temperatures, suitable for battery modules or inverter systems.
Silver-plated copper wire: Used for high-frequency conductivity or high-reliability scenarios, with lower contact resistance.
Multi-layer surface protection ensures the braided wire maintains stable conductivity under complex operating conditions.
Flexible Insulation and Protection Design
A variety of insulation and protection materials are available, including PVC, silicone, heat shrink tubing, and PET braided mesh, preventing mechanical wear, improving Round Braided Stranded Flexible Cords appearance, and facilitating equipment wiring and maintenance.
Design Advantages
Low-Stress Design Concept
The Braided Tin Coated Copper Flexible Connectors utilize a flexible design structure, effectively absorbing stress changes caused by thermal expansion or vibration during equipment operation, preventing bolt loosening or terminal damage.
Modular Assembly Interface
The end structure can be customized according to customer equipment interfaces: round holes, elongated holes, fork-shaped, square openings, etc., supporting seamless connection with standard Copper power braids, busbars, or bus trunking systems.
High interface precision and fast assembly efficiency reduce human error.
Highly Compatible Cabling Solution
The flat design saves installation space and is suitable for compact equipment structures; it can also be used in multiple layers to increase current-carrying capacity.
Whether it's connecting power battery modules or conducting current within the cabinet, stable performance is maintained.
