Electrical Power Transformer Description

Electrical Power Transformer oil-immersed with power rating from 25 to 2500 kVA and Voltage 6-36/0,4 (0.23)kV. In 50/60 Hz power transmission and distribution system for power supply and lighting in industrial and agricultural field. Distribution transformers are produced with nominal Voltage in primary winding 6 up to 36 kV. Nominal Voltage in secondary winding is 0,4 or 0,23 kV. Scheme and connection group of windings U/Un-0 or D/Un-11, etc. .On the customer demand it is possible to make transformers with different connection of the Voltage s and other construction solution. Regulating the Voltage is made as a result of moving the switch, by the transformer detached from the net both high (HV) and low (LV) Voltage s. The Voltage is being regulated on the side of HV for ±2x2,5% value from nominal value. Exterior introductions HV and LV are removable and passers-by are made from china insulators. At great current 1000 A and more on the hard core current are contact clamps screwed properly with the spatula which connecting the track or the cable attachment assures. The expandability of oil assures appropriate works of the transformer at different weather conditions and fluctuations of the temperature. The dehumidifier is installed to provide dry air in transformer. For measuring the temperature of upper layers of oil on the casing a thermometer is installed. Transformers with power rating from 400 to 2500 kVA are occupied with wells to install in base.

Electrical Power Transformer Advantages:

1. Great ability of short circuit resistance
2. Cold rolled silicon steel core and oxygen-free copper wires, higher efficiency and lower loss;
3. Complete sealed structure, low maintenance;
4. Vacuum oil filling prevents air bubbles, high stability of insulation;
5. Excellent rated capacity.

6 .The cancellation of oil conservator makes the transformer more convenient to use;

The replacement of oil tube into corrugated tank makes the transformer easier to cool;

The physical property of corrugated tank increases the reliability of the transformer;

The adoption of sanforizing makes sure the robustness of long distant transportation.
