Low Voltage Insulating Tubes


Low Voltage Insulating Tubes

REPL heat shrinkable low voltage insulating tubes (RIMT) provide an environmental protection to the cable cores of plastic and paper insulated cable termination and insulation over the connector area in straight through cable joints rated up to 1 kV. The insulating tubes are made from thermally stabilized, cross linked, weather resistant polymeric material.
 
The tubes can be supplied internally coated with hot melt adhesive.
