653/Universal Cable Gland (Group 1 Mining)
Application
Outdoor or Indoor use.
For use with single wire armoured ‘W’, wire braided ‘X’ and steel tape armoured ‘Z’ elastomer and plastic insulated cables.
For use in all mining applications particularly those 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.
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.
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 armour clamping, using one clamping arrangement for W, X & Z armour/braid types.
Provides a cable retention seal onto the cables outer sheath.
Seal manufactured from a low smoke and fume, zero halogen material.
Two part sealing compound and assembly instructions are supplied with the Cable Gland.
