Cast Resin Transformers for Power and Distribution
Cast Resin Transformers
TMC is the leading Australian manufacturer of cast resin power and distribution transformers. TMC produces cast resin transformers with capacities up to 30MVA and voltages up to 36kV. Cast resin transformers contain no oils and are environmentally inert.
The transformers are suitable for use by power distribution companies, private facilities such as city buildings, factories and mines and where environmental and fire restrictions limit the use of oil filled transformers. The cast resin transformer is the transformer of choice for indoor use and has found wide acceptance for outdoor use.
The transformers can be supplied in enclosures to various degrees of protection, or open (un-enclosed) if preferred. Enclosure ratings of IP21 to IP33 are common and protection up to IP66 is also available for extreme conditions and flameproof applications.
Enclosures are fitted with sealed marshalling boxes fitted with temperature and performance monitoring equipment. Enclosures can be fitted with interlocked doors to provide additional safety.
TMC cast resin transformers can be supplied with fans and controls to increase the rated capacity (kVA). Forced directed air circulation permits a continuous power increase of up to 35% above the rated capacity.
Fans can be used to economically provide extra capacity for overload conditions such as cyclic load peaks and traction loads.
