CMP Barrier Glands (Explosion Proof Cable Glands)

Explosion proof barrier glands provide a flameproof compound seal, outer sheath seal and universal armour clamp for steel wire armoured (SWA) and galvanised steel braided (GSWB) cable termination. A barrier gland is an Ex d cable gland incorporating a compound filled chamber sealing around the individual cores of the cable to maintain the flameproof integrity of the electrical equipment. A barrier gland must be used where the standard method of cable glanding (elastomeric seals) an Ex cable entry is considered unlikely to maintain the integrity of flameproof electrical equipment and contain an explosion within the electrical enclosures due either to cable construction or degree of explosion risk.

The cable gland provides mechanical cable retention and electrical continuity via armour termination. A combined detachable armour cone and compound tube, together with AnyWay universal clamping ring arrangement allows the cable to be easily disconnected from the equipment, for maintenance and change out etc., and re-connected with the same consummate ease. This feature also facilitates remote make off procedures when the termination is to be conducted in confined spaces or in areas of restricted access.
