Generic Cable Considerations
Unarmoured Cables When cable glands are designed to suit a range of different cable types they will often provide basic sealing and mechanical retention through the use of a sealing ring on the cable outer sheath, for example, in the case of an unarmoured or screened cable. Cable gland solutions for unarmoured cable would need to cater for a reasonable acceptance range so that the most popular cables fit comfortably within the minimum to maximum range.
Read moreEarth Tags & CIEL (Cast Integral Earth Lug)
In the event that cables have a high fault current carrying capacity, via their single wire armour configurations, the fault rating of the cable may be higher than those of the standard CMP earth tags. In this case it would be inadvisable to use standard earth tags, as it is important to match the rated fault current of the earth tag to the corresponding fault current rating of the cable armour.
Read moreEquipotential bonding
Potential equalization involves all exposed and peripheral conductive parts being connected to the equipotential bonding system. Connections to the bonding system would usually include metal conduits, metal cable sheaths and steel wire armouring (or other types of metallic armour) as well as protective conductors and metallic parts of structures. IEC 62444 requires the equipotential bonding of cable glands for braided & armoured cables to be checked after cable anchorage tests are performed.
