Braided Copper Flexible Wire Connectors
Products Description
Braided copper flexible wire connectors are functional connection components with current transmission as their core and structural flexibility as an additional engineering attribute. They are mainly used to replace or supplement rigid busbars, cables, or rigid connectors.
Their core function is not that of an "ordinary wire," but rather:
A flexible compensating conductor under high current conditions
A stress relief and vibration isolation component within equipment
A structural fault-tolerant connector in multi-point assembly systems
In engineering design, it serves as both a conductor and a structural buffer unit.
Material Advantages: Electrolytic-Grade Purity as the Foundation
Electrical Performance: T2 Grade High-Purity Oxygen-Free Copper: Copper content ≥ 99.95%. Extremely low internal resistance means minimal Joule heat loss under long-term heavy-load operation, significantly improving energy utilization.
Surface Protection Options:
Bare Copper: Suitable for clean, dry indoor electrical environments.
Tinned Copper: Provides excellent resistance to oxidation and salt spray corrosion, extending service life in harsh environments and ensuring constant contact resistance over the long term.
Silver Plated: Provides ultimate conductivity and contact stability for high-precision laboratory equipment or high-temperature superconducting applications for Twisted Copper Wire.
Technical Features: Solving Engineering Problems in Complex Operating Conditions
Superior Vibration and Fatigue Resistance
In high-vibration environments such as railway locomotives, wind turbines, and electric vehicles, traditional rigid connections are prone to fatigue failure. The Lithium-ion Batteries Connectors mesh structure disperses mechanical vibrations across thousands of fine copper wires, absorbing energy through minute relative displacements. This structural design gives the product an extremely high fatigue resistance level, capable of withstanding millions of vibration cycles without failure.
Excellent Thermal Expansion Compensation Capability
When a large current passes through the Flexible Insulated Copper Busbars, the temperature rise causes the metal to expand. Different materials and lengths of components have different coefficients of expansion, generating significant thermal stress. Flexible connectors, through their inherent elasticity, can absorb this displacement difference caused by thermal expansion and contraction, preventing equipment deformation or loosening of connection bolts.
Excellent Heat Dissipation Performance
Compared to solid conductors, braided wires have a larger surface area in contact with air, and the gaps within the braided layers facilitate air convection. This structural design allows the heat generated by the Copper Braided Busbars For Electrical during operation to be dissipated quickly, effectively reducing temperature rise and allowing it to operate safely at higher current densities.
Application Advantages: Practical Verification Across Multiple Fields
New Energy Vehicles (EV/HEV)
Within the power battery pack, there are subtle dimensional tolerances and continuous vibrations between cells and between modules and the battery management system. Our Flat Copper Braided Wire perfectly fits the compact space of the battery pack, absorbing the energy from bumps during vehicle operation and ensuring flawless electrical connections in the high-voltage circuit. Their high and low temperature resistance fully meets automotive-grade standards.
Transformer and Generator Industry
Installing Braided Wire Copper Bus Bar between transformer winding leads and bushings prevents lead breakage due to vibrations during transportation or operation. Simultaneously, it compensates for thermal expansion and contraction of copper busbars caused by load changes, avoiding oil leakage problems caused by uneven stress on sealing gaskets.
Industrial Switchgear and Power Distribution Systems
In drawer-type switchgear, where drawers need to be frequently pushed in and pulled out, flexible connectors must be used for the input and output lines. Our Copper Braided Wires are wear-resistant, bend-resistant, and can withstand tens of thousands of insertion and removal operations without affecting conductivity.
Electrolytic Coating Industry
In electrolytic cells that require the passage of huge DC currents, braided copper flexible connectors have become the preferred conductive busbars due to their extremely low voltage drop and excellent heat dissipation, significantly reducing power loss.
