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 moreCable 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.
Read moreNon-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.
