Cu Flexible Busbar
Products Description
Cu Flexible Busbar is a flexible current transmission component made by compounding high-purity copper materials and insulating materials. It achieves flexibility through multi-layer copper foil lamination or copper strip bending processes, mainly used in current connection scenarios in power systems that require adaptation to vibration, displacement, or irregular installation spaces, and is suitable for high-low voltage equipment and new energy devices in the B2B field.
The product combines "flexible adaptability" and "high conductive stability". It can bend and twist within a certain range, solving complex installation angle or equipment vibration scenarios that traditional rigid copper bars cannot adapt to, while maintaining the excellent conductive performance of copper materials to ensure the continuity and reliability of current transmission.
Flat Copper Braids fully complies with international electrical connection standards. It supports customization according to customers' equipment current levels, installation space dimensions, and insulation level requirements, and is compatible with various electrical components such as circuit breakers, transformers, reactors, and battery modules, meeting the assembly adaptability of different engineering scenarios.
Manufacturing Advantage
Professional Production Team
The core technicians have over 10 years of experience in copper processing and electrical component manufacturing, familiar with application standards in automotive, industrial, and energy fields, accurately controlling technical parameters of Flexible Connectors from design to production.
Advanced Processes and Equipment
High-precision copper foil slitting machines (slitting accuracy ±0.03mm), multi-layer copper foil laminators (pressure uniformity error ≤3%), automatic insulation coating equipment (coating thickness deviation ≤0.1mm), and flexible bending setting machines ensure dimensional accuracy and stable flexibility of Soft Bare Copper Wires.
Full-Process Quality Control System
From incoming material inspection (copper purity, insulation material temperature resistance test), in-process inspection (copper foil bonding degree, insulation coating integrity check) to finished product factory test (conductivity, insulation withstand voltage, flexible fatigue test), each link is supervised by professional quality inspectors to ensure product qualification rate.
Detail Display
| Marking and Traceability Details | Unique serial numbers, specification parameters (current level, insulation level, length) and production dates are laser-engraved on the surface of Soft Copper Tinned Wires, facilitating customer inventory management and product traceability. Installation direction markings are also engraved to avoid failures caused by wrong installation direction. |
| Installation and Fixing Details | Preset installation holes (aperture customized according to customer needs) are set at both ends or the middle of the product. Reinforced insulation design (local thickened insulation layer) is applied around installation holes, preventing short-circuit risks caused by contact between installation bolts and conductive copper, and facilitating quick on-site fixing. |
| Conductive Layer Protection Details | Edges of conductive copper foil layers are treated with covered insulation (insulation layer exceeds copper foil edges by 1-2mm), avoiding oxidation of copper foil edges or damage to insulation layers, and reducing mechanical damage to copper foil layers during transportation and installation, ensuring stable conductive performance. |
Scenario Adaptation Refinement
New Energy Vehicle Field
Used for flexible connections between cell modules in power battery packs, the Flexible BusBar Copper adapts to the compact internal space of the battery pack and the vibration environment during driving. It prevents poor cell contact caused by rigid connections under vibration, reduces the internal wiring complexity of the pack, and improves energy transmission efficiency.
01
Energy Storage System Field
Applied to connection between modules and converters in energy storage battery cabinets, it adapts to irregular installation spaces (e.g., cabinet corners) in energy storage cabinets, no need for customized special-shaped rigid copper bars, reducing design and manufacturing costs, and facilitating later replacement and maintenance of battery modules.
02
Industrial High-Low Voltage Equipment Field
Used for connection between circuit breakers, disconnectors and busbars in high-low voltage switchgear, Cu Flexible Busbar adapts to complex component layout inside switchgear, reducing internal space occupation of cabinets, and absorbing mechanical vibration during switch operation, improving switchgear operation stability.
03
Rail Transit Field
Used for connection between traction converters and motors in train traction systems, it adapts to vibration and temperature changes (-40℃ to 80℃) during train operation, avoiding insulation wear of traditional cables due to vibration, and has high current-carrying capacity (up to 1000A or more), meeting high-power needs of traction systems.
