Oil Cooled Transformers for System Earthing
Oil Cooled Transformers
TMC has a long and successful history of production of oil cooled transformers. TMC produces oil cooled transformers with capacities up to 30MVA and voltages up to 72kV.
TMC oil cooled rectifier transformers are designed, manufactured and tested in accordance with the latest issue of IEC and Australian standards according to customer specifications.
Oil cooled earthing transformers are available in single phase and three phase. Single phase earthing transformers are used between the system neutral and earth.
Three phase earthing transformers are used where there is no neutral available and can be supplied with an auxiliary winding for supply of power to other circuits.
TMC oil cooled transformers can be supplied with fans and pumps to increase the rated capacity (kVA). Forced directed oil circulation and/or forced air cooling of radiators permits a continuous power increase of up to 25% above the rated capacity.
Fans can be used to economically provide extra capacity for overload conditions such as cyclic load peaks and traction loads.
