Custom heat shrink insulated copper busbar for EV batteries, energy storage, switchgear and power distribution. Supports OEM bending, punching, plating and insulation design.
Our Heat Shrink Tube Insulated Copper Busbars are engineered to provide exceptional electrical insulation and durability for various applications. This busbar is forming a tight insulation layer by covering heat-shrinkable tube on the surface of copper busbar. The material is radiation cross-linked polyolefin or environmentally friendly halogen-free flame retardant polymer with excellent electrical properties, temperature resistance and mechanical strength. This product is not only used to improve the insulation protection level of busbar, but also can shorten the distance between phases, adapt to the trend of miniaturization of switchgear, and at the same time, it has the functions of antirust, anti-villain short-circuit and so on.
