TMGF Series Oil Distribution Transformer 1000 kVA for Industrial Applications

Transformers oil transformers of TMGF series are designed for operation in power grids with voltage of 6 or 10 kV in open electrical installations under conditions of moderate climate (execution U1 and UHL1 according to GOST 15150-69) and serve for reduction of high voltage of supplying power network to the established level of consumption. Rated power: from 400 to 1000 kVA. 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 commissioning, but not more than 4 years from the date of shipment.
