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.
Enclosures
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.
Fan Cooling
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.
