Oil transformers type TM

Three-phase industrial oil immersed transformers with capacity ratings from 25 up to1600 kVA designed to be mounted on the outside and inside buildings.

To increase the cooling surface of oil immersed transformers type TM with a capacity from 25 up to 1600 kVA with conservator is used radiator or corrugated walls.
Distributions three-phase transformers TM are produced with nominal tension in primary winding 6; 10, 15,75; 21 kV. Nominal tension in secondary winding is 0,4 or 0,23 kV. Scheme and connection group of windings Yyn-0, Dyn-11, Yzn-11.

Design features

Oil transformers TM series are equipped with oil conservator (cylindrical tank), which ensures the presence of oil under all operating conditions of the transformer and the external temperature fluctuations.
In order to protect the oil from external weather conditions on conservator is mounted silicone dehumidifiers.
The dryer is filled with a sorbent which absorbs moisture before the entry air from outside inside the transformer.
To check the oil level on the side of the conservator is mounted floating magnetic oil level indicator.
To check the temperature in the upper layer of oil in the transformer tank is mounted thermometer.
Oil transformers with capacity ratings above 1000 kVA are provided with a Bochholz relay.
