Oil Cooled Transformers for Power and Distribution

TMC has a long and successful history of production of oil cooled power and distribution transformers. TMC produces oil cooled transformers with capacities up to 30MVA and voltages up to 72kV. The transformers are suitable for use by power distribution companies and private facilities such as factories and mines and other high-voltage, high-power outdoor installations. TMC oil cooled power and distribution transformers are designed, manufactured and tested in accordance with the latest issue of IEC and Australian standards according to customer specifications.

Fan Cooling

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.
