Transformer power three-phase TM 25 kVA

Power transformer three-phase TM 25 kVA, sold by the company Energospecservice, order, consultation +38(096) 40-60-989, +38(04333)4-22-19.

Power three-phase two-winding step-down oil transformer of general purpose with a capacity of 25 kVA with a voltage of 6 kV and 10 kV is intended for the needs of the national economy, internal and external installation.

TM-25 kVA 10 (6) kV power transformers are produced with a nominal voltage of the primary winding (high voltage) up to 10 kV inclusive and the secondary winding (low voltage) - 0.4 kV. Scheme and group of connections - U / Un -0; D / University-11.

The voltage is regulated without excitation. For this, TM transformers are equipped with high-voltage switches, which are connected to the high-voltage winding and allow to adjust the voltage in stages when the transformer is disconnected from the network on the LV and HV sides with a range of +2x2.5%.
