CORROSION PROTECTION TUBINGS

APPLICATIONS:-

Heat shrinkable corrosion protection tubes provide and environmental sealing for straigth through cable joints for plastic and paper cables upto 36 kv. The tubes are made from thermally stablized, cross linked, weather resistant polymeric material. The tubes are internally coated with hot melt Adhesive.

  • All dimensions are in mm
