Application
Outdoor or Indoor use.
For use with conduit incorporating individual insulated conductors or for particular use with:-
a) Cables that are not effectively filled, compact and/or circular, have tape bedding or have hygroscopic fillers.
b) Cables that exhibit ‘cold flow’ characteristics.
c) Enclosures containing an ignition source in gas group IIC areas or containing an ignition source in a Zone 1 area and exceeding 2 litres in volume.
Features
Provides a barrier seal between the individual insulated cores within the cable and prevents entry of the products of an explosion into the cable or conduit.
Seals conductors at entry to enclosure via conduit or enables an existing Cable Gland to be converted to a barrier type Cable Gland.
The device is fitted with a simple compound filled chamber which permits packing around individual insulated conductors.
Assembly of the Cable Gland compresses and distributes the compound evenly to create a barrier seal at the point of entry into the enclosure.
The compound chamber may be separated from the cured compound to ensure that the chamber has been effectively filled. If required, external voids can be repaired.
Provides female running coupler for Cable Gland or conduit entry.
Two part sealing compound and assembly instructions are supplied with the Cable Gland.
