MPG1-1 1kV Heat Shrinkable Tube for Busbar

Introduction of Insulated Tubing for 1kV Busbar
The heat shrink tubing is made by bombarding crosslinked polyolefin heat shrinkable material with high-energy electron beam. 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 heat shrink sleeve can provide high dielectric strength and track resistance. Our bus bar heat shrink tubing has passed national certification, and can be applied to corrosion protection and insulation of busbar and electrical equipment.
