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.”

Medium Voltage Switchgear Project
For a substation of SNE in Chad, contractor Deba opted for SGC’s DF-2 program. All our products are built to last and meet the highest technical standards. The DF-2 line is specially designed to function properly in exceptional environmental conditions. For example, the metal-enclosed air-insulated medium voltage cubicles can withstand extreme heat. Ideal for the steppe climate of the Sahel region, where temperatures can rise to 50 degrees.
Not only for these reasons, Deba opted for the DF-2 medium voltage switchgear from SGC. But also for the modular concept where the combination of cubicles is unlimited. Very complex diagrams of distribution and transformer switchgear can be compiled through this extensive spectrum of possibilities.
For this project, a medium voltage substation was designed and assembled in collaboration with Deba and CUSTOMIZED to the needs of the end customer SNE (Société Nationale D‘Électricité)
Type of security cubicles?
The cubicles can be equipped with the most diverse and wide-ranging options. The customer chose cubicles of the type DF-D/EDN: protection cubicle with vacuum circuit breaker, block current transformers and equipped with a MICOM relay from General Electric at the request of the client, because they have experience with it. The relay will be programmed here by the end customer according to the selectivity study of the network in Moundou during the FAT study.
Why choose the container solution?
DF-2 medium voltage cubicles pre-tested, installed and wired in a container. A fast, cost-efficient and reliable medium voltage solution. This is the reference project and trendsetter for sustainable substations supported by FIT (Flanders Investment and Trade). We expect similar projects to be required for the expansion of the installed capacity in Chad. In fact, they have an acute shortage of generation capacity out there.
Are you also looking for built to last medium voltage switchgear? At SGC you are at the right place!
Don’t hesitate to contact us for your project. We will be happy to discuss it.
