Ampcontrol is helping a mine in New South Wales, Australia, boost output following the delivery of new high voltage infrastructure.

The mine, which has taken its production from 6.4 Mt/y to 7.5 Mt/y, engaged Ampcontrol for a design, manufacture and installation project, which included a 40/50 MVA transformer, c/w 11 kV substation, 3,000 A 11kV switchboard and associated protection system.

As part of the project Ampcontrol designed, manufactured and tested a 40/50 MVA 132/11 kV transformer, with a final fully assembled weight of 85 t.

The transformer was fully tested in-house at Ampcontrol’s transformer facility, before being filled with oil above the core and coil assembly for transport to the mine where site erection work was undertaken by Ampcontrol’s High Voltage Service team.

The transformer will be energised at a later date during major site shutdown works, Ampcontrol said.
