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 :
- High shrink ratio.
- Excellent machanical properties.
- Hot melt adhesive provide perfect environmental seal on cable sheathe.
- Excellent resistance to weathering. moisture, Contamination and adverse environmental conditions. Lightweight and Flexible.
- Excellent resistance to UV rays, Ozone, chemicals & solvents.
- Provides machanicals starain relief.
- Easily Re- enterrable.
- Also available in spools
- Confirms to IEC 60684-3-247 standard.
- Customised dimesion, thickness, length & colour available on request
- Meets IP 68 (Ingress Protection)
