ZEN Insulated Cable Glands
ZEN is available with an insulating arrangement to ensure that no contact is made between the earth circuit carried through the cable armour and the electrical enclosure which the cable enters. This isolation of the cable armour at one end of the cable is sometimes referred to as single point earthing. The ZEN range from CMP however allows more than a single point of earthing and delivering optimum safety.
