Additional Information

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.

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.

Sheath Material Mechanical Properties

When specifying, selecting, evaluating or assessing cables, the type of material used for the sheathing should always be taken into account. Some of the standards mentioned above have very specific requirements for the tensile strength of cable sheathing, and in some cases these may be less than that required by IEC 60079-14.
