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%.

110kV Three-phase power transformers ТДТН, ТМТН type

ТДТН, ТМТН type transformers: three-phase, three-windings, with natural oil circulation and forced air blowing (ТДТН) or naturally air cooling (ТМТН), with on-load voltage regulation (РПН) on the HV (high voltage) side and off-load switching (ПБВ) on the MV (medium voltage) side. The transformers are designed to convert AC high voltage of 110 kV to medium voltage (35 kV) and low voltage (6-10 kV) power and maintaining a predetermined voltage level in the distribution grids of both industrial areas as well as in general purpose electric grids.
