HEAT SHRINK MEDIUM VOLTAGE INSULATION TUBING QDWT SEMI-CONDUCTING / INSULATION, DOUBLE LAYER, UP TO 36kV HEAT SHRINKABLE TUBING SHRINK RATIO 3:1 Features/Applications QDWT is double layer semi-conductive heat shrinkable tubing. The inner layer is made from insulation material to provide high insulation and the external layer is made from semi-conductive materials to provide electric shielding. The tubing is manufactured with technology very suitable for applications in power cable joints up to 36kV. Operating temperature: -45°C to +100°C Minimum shrink temperature: 100°C Full Recovery Temperature: 130°C Standard color: Black RoHS Compliant Two layer Semi-conductive Specification Values for Inner Layer Test Method Typical Data Tensile Strength ASTM D 2671 > 12 MPa min.
