MPG5-40.5 Insulated Tubing for 40.5kV Busbar

Introduction of Insulated Tubing for 40.5kV Busbar
The heat shrink tubing is made by bombarding crosslinked polyolefin heat shrinkable material with high-energy electron beam, and environmentally harmful substances such as PBB, PBBD, PBBE and heavy metals are restricted. When burned, the heat shrink tubing does not generate poisonous gas or hazardous substances, and the heat shrink sleeve can provide high dielectric strength and track resistance. Our heat shrink tubing is a certified product, and can be applied to corrosion protection and insulation of busbar and electrical equipment.
