Introduction of Insulated Tubing for 12kV Busbar
The bus bar heat shrink tubing is made by using high-energy electron beam to bombard crosslinked polyolefin heat shrinkable material. Environmentally harmful substances such as PBB, PBBD, PBBE and heavy metals are restricted. When burned, the bus bar heat shrink tubing does not generate poisonous gas or hazardous substances, and the shrink tubing can provide high dielectric strength and track resistance. Our bus bar heat shrink tubing is a certified product, and can be applied to corrosion protection and insulation of busbar and electrical equipment.
