Copper bar / crossing bar Isolams

Effective for devices with high current capacity! Insulated flexible busbar.

"Iso-Rams" is an insulated flexible busbar made by laminating a highly flexible strip copper conductor and coating it with self-extinguishing black PVC resin. It can connect to various devices and copper busbars with different laminated copper strip widths. It is particularly effective for electrical equipment with high current capacity. Additionally, it has a smaller temperature rise compared to cables and bare copper busbars, and its laminated structure reduces the increase in AC resistance due to the skin effect. 【Features】 ■ Wide range of conductor sizes: 21–1200 mm² ■ Can connect to various devices and copper busbars with different laminated copper strip widths ■ High insulation performance ■ Smaller temperature rise compared to cables and bare copper busbars ■ Reduces the increase in AC resistance due to the skin effect *For more details, please refer to the PDF document or feel free to contact us.
