Barrier gland what is

Shortened lifetime for the glands and the cable entries can result if incompatabile materials selected. Barrier glands are similar to normal cable glands, except a compound sealant material is used to seal around the individual cores of the cable ensuring the inside of the cable is gas tight as well as the outside.

When Should a Barrier Gland be Used? No resin. No mixing. No cure time. Simply pass the individual cores through the pre-punched seal, fill any unused holes with the provided sealing pins and tighten. Fully inspectable and no waiting time — irrespective of temperature, location or installation position.

The seal is manufactured from a silicone material, has LSFZH properties, is o-zone and oil resistant and suitable for use at both high and low temperatures. The Rear Sealing System covers the entire range of cable diameters with out the need for special seals and the cable acceptance range is stamped on the backnut for ease of inspection. With a unique clear non-metallic compound chamber for both IEC and NEC application, the barrier seal can be made using either a QSP quick setting 2-part hand-mixed putty, or a liquid injectable and fast curing resin, allowing for faster installation time than traditional 2-part compounds.

The transparent compound chamber allows full visibility of the flameproof seal during installation and inspection making the ExPress barrier resin unparalleled as a global solution. Simply by reversing the clamping ring, the cable gland can adjust to accommodate all types of cable armour or braid. Unlike many of our competitors, the correct stamping orientation is marked clearly with the armour size and backed up by the presence of a groove in the component.

Without the need for fiddly measuring systems, the guide provides a permanent visual indication of the gland tightness through installation, inspection and maintenance.

The backnut, once tightened to the line corresponding to the cable diameter, ensures there is no cable damage whilst still maintaining IP and pull-out.
