Additional Information

Cable Gland Sizing – Cable Construction & Armour Wires

Cable glands conforming to British Standard BS 6121:1973 were specifically to cater for industry standard armour wire sizes and cable diameters found in British and international standard cables. These armour wire sizes have remained common to virtually all cables manufactured to BS, IEC and AS/NZS standards, and can be accommodated by some industrial cable glands to BS 6121 & IEC 62444 and explosive atmosphere certified cable glands to IEC 60079. There is an expectation that within a given armoured cable, all of the armour wires have the same consistent thickness so that cable glands utilising a cone and clamping ring can be correctly terminated and maintain their safety critical functional performance. If the armour wires in an armoured cable have significant differences in their thicknesses then it may be no surprise if consequent issues arise with their termination when using standard products. The correlation between the cable inner bedding diameter and the cable armour wire is clearly defined in IEC 60502-1 and AS/NZS 5000.1.

Non-Standard Armour Wire Sizing

Due to the global nature of cable manufacturing, and variations from one supply country to another CMP also provides alternative cable glands to suit cable armour wires which are outside of the standard range. This predominantly affects Single Wire Armour (SWA) cables and the data provided below is geared towards that type of cable. Most variations in braid thickness can be accommodated with standard product.

Explosion Protected Equipment

For equipment which is intended to be used in explosive atmospheres, a number of standard methods of protection against ignition have been established. These have been adopted into construction standards and codes, which allow manufacturers to make equipment of a uniform type and have this equipment tested and certified for compliance with the relevant standards.
