DF-2-air insulated switchgear successfully installed in Queensland (Austrialia) by our reseller NHP

Check out the case study from our reseller NHP

NHP was proud to assist in upgrading the Oxley Creek Sewage Treatment Plant in South East Queensland for flood resilience and optimising operations with a healthy and efficient electrical design.

The Solution: DF-2-air insulated switchgear module with built-in arc quenching system ‘Arc Killer’

The project included decommissioning the original high-voltage switchroom and the 11kV main switchboard for the site, and replacing it with a new main 11kV switchboard contained within a demountable building. The building was also raised 30cm above the 2011 peak flood line levels.

Within the switchroom, NHP specified the DF-2 air-insulated switchgear module with demountable vacuum circuit breakers and a remote operation functionality. Exclusive to NHP switchgear, the cubicles were specifically designed to minimise the consequences of an internal arc and forming a key component of this, is a built-in arc quenching system “arc killer”, which can extinguish an arc in less than 50ms.

“NHP were able to design, supply and install a solution for Queensland Urban Utilities that not only meets local requirements, but delivers an advanced technology which only NHP offers to the market.”
