transformer TM 25-1000/10(6)/0,4 U1

Oil transformers TM are produced with capacity from 25 to 1000 kVA nominal primary voltage 6 or 10 kV and rated the voltage of the secondary winding of 0.4 or 0.23 kV, 50 Hz. Scheme and the connection group of the windings U/UN-0 or D/UN-11.

Type of climatic performance U1 according to GOST 15150.

The normal operation of transformers is provided under the following conditions:

1.The height above sea level not exceeding 1000m;

2.Environment – not explosive, not containing conductive dust, aggressive gases and steams in concentrations, reducing the parameters of KTP in the invalid range;

3.Wind speed up to 36 m/s (speed of wind pressure up to 800 PA);

4.Atmosphere type II by GOST 15150;

5.Ambient temperature - from -45°C to +40°C.

Voltage regulation is performed by switching without excitation (DBW) when disconnected from the network transformer like from the top so and low voltage. Voltage is adjustable from the top voltage for a ±2x2,5% from the nominal value.

Transformer bushings for outdoor installation, removable insulators bushing porcelain. When currents of 630 a and 2500 A on the busbar terminals attached terminals with the blade, which provides connecting bus or cable lugs.

Malorussian ensures the presence of oil under all modes of operation of the transformer and the temperature fluctuations of the environment, and has built-in air dryer with oil shutter.

To measure the temperature of top oil layer on the lid mounted thermometer.

Transformers with capacity of from 400 to 2500 kVA are equipped with rollers.

Transformers 116777 comply with GOST and technical conditions
