Power transformer three-phase two-winding, step-down, oil, capacity 25-1000 kVA

Power transformer three-phase two-winding, step-down, oil, with a capacity of 25-1000 kVA, sold by the enterprise Energospecsservice, order, consultation +38(096) 40-60-989, +38(04333)4-22-19.

Power three-phase two-winding step-down oil transformer of general purpose with a capacity of 25-1000 kVA with a voltage of 6 kV and 10 kV is intended for the needs of the national economy, internal and external installation.

Power transformers TM-25-1000 kVA 10 (6) kV are produced with a nominal voltage of the primary winding (high voltage) up to 10 kV inclusive and the secondary winding (low voltage) - 0.4 kV. Scheme and group of connections - U / Un -0; D / University-11.

The voltage is regulated without excitation. For this, TM transformers are equipped with high-voltage switches, which are connected to the high-voltage winding and allow to adjust the voltage in steps when the transformer is disconnected from the network on the LV and HV sides with a range of +2x2.5%.

TM transformer operating conditions

Height above sea level - up to 1000 m.

Ambient air temperature:

- for a moderate climate - from -45 0С to +40 0С (execution U);

- for a cold climate - from -60 0C to +40 0C (HL version).

Relative air humidity - no more than 80% at +25 0C.

TM transformers are not designed to work:

- in an explosive and aggressive environment (containing gases, evaporation, high concentration dust, etc.);

- with vibration and shaking;

- with frequent switching on of the power supply up to 10 times a day.
