Insulated Copper Busbar System
We provide insulated busbar solutions designed for high-voltage energy storage systems up to 1500V.
Available Insulation Treatment Processes：
Epoxy powder coating
Epoxy powder coated copper busbar with custom Z-bend geometry, fully insulated except precision-cut terminals.
Uniform, pinhole-free epoxy coating on complex profiles, with consistent coverage even on sharp corners and edges
Clean terminal cutouts with no coating overhang, and wrinkle-free insulation on tight-radius bends.
High-adhesion epoxy insulation with no peeling at edges, paired with burr-free copper terminals for reliable connections.
PVC dip coating
Full PVC dip-molded insulation on shaped copper busbar, seamless coverage over the entire profile, with precision-exposed terminals for easy installation.
Clean, cut-back insulation at terminals, with no coating overhang or burrs, ensuring flat, reliable contact
Clean, cut-back insulation at terminals, with no coating overhang or burrs, ensuring flat, reliable contact
Heat shrink insulation
Custom formed copper busbars with full PE/PET heat shrink insulation, designed for complex 3D profiles.
Smooth, burr-free copper surface prevents insulation piercing, paired with tight-fitting heat shrink tubing for long-term reliability
Heat shrink tubing neatly terminated at terminals, with wrinkle-free coverage on sharp bends.
