Medium & Heavy Wall Busbar Tubing
Power Distribution System Applications.
Hind Polymers offer Transeal / Hongshang medium and heavy wall busbar insulation tubing engineered to deliver superior electrical insulation and mechanical protection for busbars in power distribution systems. Made from thermally stabilized, cross-linked, non-tracking and weather-resistant polyolefin, these tubes feature a nominal shrink ratio of 2.5:1, ensuring a snug fit and reliable performance. They effectively insulate copper and aluminum busbars, preventing flashovers and unintended discharges, while their robust walls enhance thermal management and mitigate the risk of short circuits, making them vital for high-current applications in industrial and commercial environments.
