    Application of Heat Shrink Bus Bar Tubes

Bus Tube is heat shrinkable tube designed to insulate busbar systems up to 36KV & to protect against accidental flashover. The tubes are manufactured from high quality non tracking crosslinked polyolefin material. Meets ANSI C37.20.2 standards for MV switchgear application up to 36 KV.

-: FEATURES & BENIFITS :-
  • Reduce Busbar clearance.
  • Prevent Busbar from chemical corrosion effected by strong acid, alkali, salt etc.
  • Solve the problem of insulation among Busbar in Bus Duct.
  • Halogen free, flame retardant.
  • High dielectric strength.
  • Highly Flexible for use on straight or angled bars without creasing.
