Two-winding power transformers with РПН, type ТМН-2500-6300/110-У1(УХЛ1), energy-efficient, with reduced losses

Power transformers, three-phase, double-winding, with natural oil circulation, equipped with on-load tap changers (РПН). Automatic control is carried out by an automatic controller supplied together with the transformer. The use of ТМН-type transformers ensures reliable power supply to the consumer throughout the entire service life.
