Ampcontrol’s Singapore team recently carried out installation, testing and commissioning of temporary electrics for Singapore’s Tuas Water Reclamation Plant.
Contracted to deliver services for the Public Utilities Board on behalf of McConnell Dowell South-East Asia, the Singapore team supplied a range of equipment and services to support the project.
This work included installation, testing and commissioning of all temporary electrics including substations, switchrooms, transformers and high and low voltage cables within the Tuas Water Reclamation Plant.

To take their current production from 6.4Mta to 7.5Mta, a central New South Wales mine engaged Ampcontrol to design, manufacture and install high voltage infrastructure. The 132/11kV project included a 40/50MVA transformer, c/w 11kV substation, 3000A 11kV switchboard and associated protection system.
As part of the project Ampcontrol designed, manufactured and tested a 40/50MVA 132/11kV transformer, with a final fully assembled weight of 85 Tonnes.
The transformer was fully tested in house in 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.
