Insulated Flexible Copper Busbar For Switch Cabinets
Product structure and materials For Insulated Flexible Copper Connector
Conductor section
● Material: T2 purple copper foil/copper stranded wire (copper content ≥99.95%), high purity, excellent electrical conductivity
Structural form:
● Laminated type: Multiple thin copper foils are stacked together, with strong current-carrying capacity, suitable for high-current scenarios
● Twisted type: Multiple strands of fine copper wire twisted together, with high flexibility, suitable for environments with frequent bending
● Woven type: Copper wires are woven into a mesh, which offers the best flexibility and is suitable for complex spatial connections

Adapt to scenarios |
New energy vehicle battery packs, UPS systems, High and low voltage switch cabinets |
Rail transit traction converters, Industrial electric arc furnaces, Energy storage power stations |
Core advantage |
The laminated structure reduces the skin effect, with less contact between the insulating layer and the conductor, high flexibility, and the ability to be folded and twisted |
It has strong seismic resistance, is suitable for equipment vibration and thermal expansion and contraction, and has better high-temperature resistance than laminated type |
The application for insulated flexible copper connector
Internal connection of switch cabinets: Replacing traditional hard connection, simplifying installation and reducing mechanical stress
Transformer outgoing line connection: Adapt to slight displacement of the transformer and reduce the risk of fatigue fracture at the connection point
Internal connection of the charging pile: Heat-resistant and moisture-resistant, ensuring the stability of high-power charging
Wind power generation equipment: Resistant to low temperatures (-60℃) and strong wind vibration, ensuring safety during high-altitude operations
