Insulcap-De-gassing (RV) is Heat Shrinkable End Caps, supplied with Relief Valve (RV) & are used for sealing High Voltage & Extra High Voltage Cables (33 kV & above) to release the constantly evolving gas generated inside the Cable during transportation & storage in hot climate conditions.
- Provides additional security to Cables by relieving the pressure generated by Residual gases.
- Valved End caps (v) available for pressurized application for Telecom cables.
- Special Relief valved End Caps (RV) available for degassing application in High Voltage Power cables.
- Live End Cap Kit available for sealing Live Cables.
- Conductive End Caps are available with Conductive Mastic.
