Heak Shrinkable Insulating Tube

All dimensions are in mmDrawing depicts typical dimensionsE – as suppliedS – after free recoveryD – internal diameter without adhesive coatingL – Length as per requirement

Heat Shrinkable Insulating Tubes are used to build up insulation over the connector area in Plastic and Paper insulated cable straight through joints rated up to 36kV. The Insulating Tubes are made from thermally stabilised cross linked high resistance polymeric material.
