Earthing is the process of creating an alternative path for the flow of fault/excessive currents safely into the ground in the presence of minimal resistance or impedance. Integral Earth Cable Glands The CCG IE gland is designed for MV and HV installations where an external protective connection with low resistance from the gland to earth is needed. The CCG IE gland range has been independently tested to the maximum short circuit fault current ratings as per IEC 62444 which are:
- 26 kA for 1 second for gland sizes 20mm to 40mm
- 43 kA for 1 second for gland sizes 50s and above.
Insulated Cable Glands The CCG Insulated gland is designed for earth neutral systems whereby the armour of the cable is isolated from the equipment in order to reduce electromagnetic interference on sensitive instruments or for stopping circulating eddy currents developing on single-core cable installations.
