TM Series Oil Distribution Transformers for Power Distribution Applications

Oil transformers of TM series are designed for operation in 6 or 10 kV power grids in open electrical installations in moderate climate conditions (execution U1 and UHL1 according to GOST 15150-69) and serve to reduce high voltage of the supplying power grid to the specified level of consumption. Rated power: <ul> <li>- For transformers of TM series: from 25 to 630 kVA;</li> </ul>Rated HV voltage: 6, 10 kV Rated LV voltage: 0,4 kV Winding connection schemes and groups: U/Un-0; U/Zn-11; D/Un-11. Different combinations of voltages and connection schemes of HV and LV windings are possible upon customer's request.

Operating frequency: 50 Hz Voltage regulation is carried out on the HV side by means of a five-stage voltage switch PBV (switch without excitation): U±2x2x2.5 % Climatic execution: ?1 (from -45°C to +40°C), ???1 (from -60°C to +40°C) (according to GOST 15150-69). Warranty on supplied products: 3 years from the date of import.
