This table compares key specifications of PE and PET heat shrink insulated copper busbars to help you choose the right insulation solution for your application.

Description:

Flexible busbars, made from thin layers of copper or aluminum foil (0.1mm to 1mm thick), offer excellent conductivity and flexibility. Flexible bus bars enhance heat dissipation, reduce vibration, are easy to install, and save space. These insulated busbars are widely used in EV battery packs, new energy distribution systems, UPS, and charging stations.
