Electro-technology company operating throughout Australia to deliver installation, maintenance and manufacturing services from inception to replacement.



Nilsen switchroom packages are designed for a very large range of applications including operation in remote areas where environmental stresses are severe. Switchrooms can be transportable, are generally of steel construction, colourbond, and also of stainless steel in areas where corrosive atmospheres are encountered. Pressurisation to prevent dust ingress, air conditioning, fitout for communication, fire alarm and fire suppression are part of the Nilsen switchroom design and manufacturing program.

Case Study

Prominent Hill Copper-Gold Mine Project
Prominent Hill Copper-Gold Mine Project Prominent Hill Copper-Gold Mine Project

Following tough competition, Nilsen Switchboards secured the project from Fluor (EPCM contract) on behalf of Oxiana for the Prominent Hill Copper-Gold Mine Project. This bolsters Nilsen’s reputation in SA’s Far North as a major package supplier.

Prominent Hill is a green field site located 100km SW of Cooper Pedy, the project will include development of an open-pit mine (480m deep x 1.4km x 1.2km), a conventional crushing, grinding and flotation processing plant with an 8mtpa capacity, construction of a permanent village to accommodate a steady-state workforce of approximately 400 and construction of a haulage road, power line and bore field.

Our contract entails the design, manufacture, installation, testing and delivery of 5 Fire Rated Switchrooms, 10 Motor Control Centres, 6 Plant Process Control Panel PLC Suites, 35 Distribution Boards (including stainless steel outdoor type), 1 stainless steel outdoor MCC and 2 associated stainless steel control panels, Water Treatment MCC and PLC package, on-site supervision & commissioning of various scopes and other minor works again demonstrating Nilsen’s diversity and ability to meet total package requirements in demanding time frames.

Future Developments:
Recent exploration testing beneath the Prominent Hill resource has returned some excellent results demonstrating that the copper-gold system extends at least twice as far as previously outlined. This bodes well for a longer mine life meaning that Prominent Hill will be an important part of the region for many years to come. Preliminary studies into the potential and possible timing for underground mining in the future have already commenced.
