E1FW/M Flameproof Ex d, Increased Safety Ex e Cable Gland
CMP Type E1FW/M Group I Certified Flameproof (Type ‘d’, Group I), Increased Safety (Type ‘e’) cable gland for use in Zone 1 Explosive Atmospheress with Single Wire Armour (SWA) cable. This cable gland provides a flameproof seal on the cable inner bedding and in addition the gas tight seal has been tested to prove compatibility with restricted breathing equipment that relies upon flammable gases being excluded from the main enclosure.
All CMP Cable Glands are EMC Tested.
The cable gland allows mechanical cable retention and earth continuity via the cable armour termination. Separate tightening actions for the inner displacement seal and the armour termination afford maximum control over the pressure applied to the cable bedding, and also allows the effectiveness of the gas tight seal to be tested. A detachable armour cone and AnyWay clamping ring arrangement facilitates remote make off and enables the cable to be disconnected from the equipment. An environmental / load retention seal is provided on the cable outer sheath.
