Heat Shrinkable Moulded Shapes
Cable End Caps - De gasing End Caps 
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.
Features & Benefits:
- Provides additional security to Cables by relieving the pressure generated by Residual gases.
- Automatically releases gas when pressure rises above 3 psi.
- Eliminates possibility of accidental fire caused due to trapped Methane gas while removing the (normal / non relief valved) End caps.
- Possibility to reduce the timing of de-gassing (heating) chamber, thereby savings in energy & time.
- Relief (Non-returnable) valve shall not allow moisture, water, dirt, etc. to enter the cable.
- Ensures gas / defect free cables, adds customer satisfaction.
- Each Relief valve is factory tested for gas release.
- Meets IP 68 (Ingress Protection)
