LOW VOLTAGE INSULATING TUBING

APPLICATIONS:-

Heat shrinkable LV insulating tubes provide and environmental protection to the cable cores of paper and plastic insulated cable termination and insulation over the connector area in straigth through cable joints rated upto 1.1 kv. The insulated tubes are made from thermally stablized, cross linked, weather resistant polymeric material. The tubes can be supplied with internally coated with hot melt adhesive.
