Stainless Steel High Voltage Range

AusProof’s Stainless Steel High Voltage Range, also known as ‘flameproof couplers’, have been in production for nearly 30 years, and are suitable for use in underground mining, underground operational sites, and Group 1 hazardous locations.

Working tirelessly to provide the industry with safe, reliable and modern equipment to give our customers peace of mind when working around high voltages, AusProof continuously looks for opportunities to enhance its products. The couplers within this range are an example of this drive to redesign and reinvent.

Thanks to the hard work and dedication of our Research and Development powerhouse, we have been able to offer the industry an alternative coupler that takes the guesswork out of flameproof path maintenance by way of the Removable Flange feature. Released in 2015, this feature has enabled the reduction of off-site maintenance costs and site downtime with its quick and simple replacement method. All that’s required is the removal of four countersunk screws to replace the flange. No specialised skills are necessary as there is no cable termination in this process, and repairs to the coupler can be conducted without risking damage to any vital components.

Available in the High Voltage Stainless Steel Range are:

  • the Ex118BSS, rated to 800 amps with a current carrying capacity of 11,000 volts; and
  • the Ex118BSSRF, rated to 800 amps with a current carrying capacity of 11,000 volts and featuring the Removable Flange.

Through the continuous drive to redesign and improve our products, our Ex couplers are able to have their glands tensioned at any time without the need to terminate any cables or remove any components.

Available as an add-on for additional operator awareness and safety is AusProof’s revamped and revolutionary LED Live Line indicator, allowing for quick and easy identification of a live and active coupler. This product has been designed so that it is battery-free to prevent false positives, and so that it does not interfere with coupler operation in any way.

Each component in the stainless steel range has been thoroughly researched and developed by AusProof to ensure that each individual part works together seamlessly to create a reliable and high quality integrated system.

Designed and developed to be compliant to AS/NZS1300:2009, AS/NZS 60079.0.2008 and AS/NZS 60079.1.2008 certification, additional features of AusProof’s high voltage stainless steel couplers include:

  • IP66 rating
  • Pilot protection
  • Higher resistance to damage on flameproof paths
  • Silicon seal for face
  • Full phase to earth segregation with earth
