Armoured Cable Glands

Armoured Cable Glandshttp://www.controlandinstrumentation.com/resources/gland.html Home Glossary Resources Armoured Cable Glands Why Do We Use Cable Glands? - To firmly secure cable entering a piece of equipment - To maintain the ingress protection of the piece of equipment (minimum of IP54 for 'e' and 'n' type enclosures. Where the enclosure wall thickness is less than 6mm a sealing washer or thread sealant will be required to maintain IP54 protection) - To maintain earth continuity between a piece of equipment and any armouring in the cable - To ensure containment of an internal explosion in flameproof equipment Is There a British Standard for Cable Glands? The Code of Practice for selection, installation and inspection of cable glands used in electrical installations is covered in BS 6121-5 1989 Mechanical cable glands. Selecting Cable Glands Items to consider when selecting a cable gland for a particular installation include: - Possibility of electrolytic action between the gland and the enclosure. Shortened lifetime for the glands and the cable entries can result if incompatible materials selected. The most common materials used are brass, stainless steel and plastic. Material choice will influence cost. - Degree of Ingress Protection required. See our page on IP ratings. - Certification of gland for use in Hazardous areas - Normal or barrier gland required - Size of cable being terminated - Size of cable entry on piece of equipment What is a Barrier Gland? Barrier glands are similar to normal glands, except a compound sealant material is used to ensure the inside of the cable is gas tight as well as the outside. When Should a Barrier Gland be Used? BS EN60079-14 Electrical Apparatus for Explosive Gas Atmospheres Part 14 - Electrical Installations in Hazardous Areas (other than Mines) provides a selection process for deciding if a barrier gland is required. There are various options to consider, however if the hazardous gas require IIC apparatus, or if the volume of the enclosure is greater than 2 litres then it is likely you will need to use a barrier gland. IIC apparatus is generally associated with Hydrogen. Gable Gland Sizing A rough gland sizing table is provided below, however reference should be made to the British Standard referenced above.
