Epoxy Powder Insulated Bending Copper Busbar
As a key connection component in the new energy power system, the Epoxy Powder Insulated Bending Copper Busbar uses high-purity electrolytic copper (purity ≥ 99.95%) as the base material. Through precision bending and forming technology and multi-layer epoxy powder coating technology, it achieves the perfect combination of flexible installation and efficient insulation. The product supports 3-12μm customized plating (silver plating/tin plating/nickel plating), and with diversified insulation solutions, it can operate stably in an environment of -45℃ to 150℃, meeting the complex wiring requirements of new energy vehicle high-voltage systems, photovoltaic inverters and other scenarios.
