110-150kV Three-phase two-windings oil-immersed power transformers ТМ, ТД type
Power range, kVA: 2500-6300 (ТМ); 10000-40000 (ТД).
Three-phase power oil transformers with natural oil circulation in the tank and natural (ТМ) or forced (ТД - blowing) air cooling are designed to convert electrical energy of power grids to reduce voltage to the level of local distribution networks, including industrial enterprises, as well as for auxiliary power. Type of voltage control - off-load (ПБВ) on HV side (switching without excitation), the control range - ± 2x2,5%.
