Braided Wire Copper Bus Bar
Products Description
Braided Wire Copper Bus Bars are essentially a type of flexible busbar system. Their design philosophy doesn't simply pursue cross-sectional area or current carrying capacity, but emphasizes long-term stable conductivity and structural reliability under complex operating conditions.
Key features include:
Multiple strands of fine-diameter copper wire are interwoven, resulting in a uniform structure and distributed stress.
They possess excellent flexibility, allowing for bending in multiple directions.
Contact surfaces can be welded, crimped, or have custom terminals as needed.
They balance low resistance, low inductance, and mechanical buffering capabilities.
This structure makes them significantly superior to traditional rigid copper busbars or single flexible connection solutions under dynamic operating conditions.
Material Advantages: Microstructure Determines Macroscopic Performance
High-purity oxygen-free copper substrate
Oxygen content <5ppm, extremely low hydrogen embrittlement sensitivity, suitable for vacuum or confined environments. Copper content ≥99.99%, total impurity elements (Fe, Pb, S) <0.001%, ensuring a conductivity decay rate of <1%/year under long-term high temperatures (>100℃), meeting the 60-year design life requirements of nuclear power equipment.
Matching Multi-element Plating System
Tin Plating (3-8μm): Optimal cost-effectiveness, suitable for -40℃~150℃, sulfur resistance meets ISA 71.04 G3 corrosion level, contact resistance stability >10 years.
Silver Plating (2-5μm): Best conductivity, suitable for high current (>1000A) and low contact force scenarios, oxidation resistance temperature up to 200℃, commonly used in rail transit traction systems.
Nickel plating (5-10μm): Offers the strongest corrosion resistance, suitable for high-salt-spray environments such as marine and chemical plants (C5-M). The galvanic corrosion potential difference with stainless steel fasteners is <0.1V, preventing electrochemical corrosion.
Co-designed insulation materials: The PVC dip-coating layer is suitable for general industrial environments (temperature resistance 105℃), while the silicone or polyimide thin coating (0.08-0.12mm) is suitable for high-temperature (180℃) and high-frequency (>10kHz) scenarios, with a dielectric loss factor <0.003, preventing insulation layer overheating. The elastic modulus of the insulation material matches that of the Braided Tin Coated Copper Flexible Connectors, ensuring no cracking during bending.
Main Functions: Providing Comprehensive Protection for Power Systems
High-Efficiency Current Carrying Capacity
Utilising high-purity copper and an optimised braided structure, Copper power braid can achieve stable transmission of large currents, adapting to power systems of different voltage levels and meeting current-carrying requirements from hundreds to thousands of amperes, with a power transmission efficiency of over 98%.
01
Vibration Absorption Function
The flexible braided structure effectively absorbs vibration and shock generated during equipment operation, preventing loosening or damage at connection points, making it especially suitable for high-frequency vibration scenarios, such as industrial machine tools and wind power equipment.
02
Thermal Expansion and Contraction Compensation Function
In environments with large temperature variations, the product can adapt to the thermal expansion and contraction of equipment through its own expansion and contraction, avoiding stress damage caused by deformation of rigid connections and ensuring long-term stable operation of the system.
03
Safety Protection Function
The high-quality insulation layer exhibits excellent flame-retardant and breakdown resistance properties, effectively preventing safety hazards such as short circuits and leakage. The surface coating enhances corrosion resistance and extends the product's service life in harsh environments.
04
Convenient Adaptability
The flexible structure and diverse connection methods allow for quick adaptation to different equipment interfaces, reducing on-site installation difficulty and time, improving engineering construction efficiency, and supporting customised designs to meet the size and performance requirements of special working conditions.
05
Value Realization and Lifecycle Advantages
Optimized Total Cost of Ownership
While the initial purchase cost may be higher than traditional copper busbars, the value created by our braided copper busbars in terms of installation, maintenance, and system reliability far outweighs this difference. Installation time is reduced by 60%, maintenance intervals are extended by 3-5 times, and system failure rates are reduced by over 70%. These factors enable the total cost of ownership to fall below that of traditional solutions within two years.
Sustainable Design
The Flex Connector features a fully recyclable design, with up to 100% copper recycling. Optimised current-carrying efficiency reduces system energy consumption, indirectly reducing carbon emissions. The long lifespan design reduces replacement frequency and waste generation. We partner with certified recycling partners to provide customers with complete lifecycle management and material traceability services.
