Features/Applications

HDWT is dual wall heat shrinkable tubing which inner layer is made

from insulation material to provide high insulation and its external

layer is made from semi-conductive materials to provide electric

shielding. The tubing manufactured with special technology, is very

suitable for applications in power cable joints up to 36KV.

 

 Minimum shrink temperature: 110°C

 Minimum fully recovery temperature: 130°C
