Heat Shrinkable Moulded Shapes
CATV - INSULTUBE Premium
Insultube-Premium (GBT) is heat shrinkable tubing, designed specifically to meet the need
of Broadband CATV industry. It provides mechanical protection and a reliable waterproof
seal of cable connectors and tap terminations. It is easy to install and shrinks to
follow the profile of the object to be protected.
it is used for insulating underground & aerial connections in CATV plant, CCTV
connections and control cables splicing joints.
General Properties :
