Copper busbar processing for distribution boards and power receiving and transforming equipment.

Processing of copper busbars for cubicles, distribution boards, and pad-mounted transformers. Proposals taking into account the insulation distance and support spacing within the panel.

Distribution boards and power receiving and distributing equipment need to safely carry large currents in the limited space within the panel, requiring design considerations that include not only the shape of copper busbars but also insulation distances, support intervals, and electromagnetic forces during short circuits. Our company responds to inquiries from transformer manufacturers and panel manufacturers, not only providing processing according to drawings but also addressing questions such as "Is this arrangement sufficient for insulation?" and "How much support interval is necessary?" We also have a track record with pad-mounted transformers (ground-mounted transformers).
