  • Cable inner sheaths that are not effectively filled, compact and/or circular, have tape bedding or have hygroscopic fillers.
  • Cables that exhibit ‘cold flow’ characteristics.
  • Enclosures containing an ignition source in gas group IIC areas or containing an ignition source in a Zone 1 area.
  • 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.
