QDWT Datasheet, PDF (1/1 Pages) Qualtek Electronics Corporation – HEAT SHRINK MEDIUM VOLTAGE INSULATION TUBING

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
