Energy-efficient, low-loss two-winding power transformers with OLTC, type ТДНС-10000÷16000/35-У1 (УХЛ1).

Power transformer, three-phase, double-winding, with natural oil circulation and forced air cooling, equipped with an on-load tap changer (РПН). Automatic control is performed by an automatic controller supplied together with the transformer. It is intended for operation in auxiliary power systems of power plants. The use of a ТДНС-type transformer ensures reliable power supply to the consumer throughout the entire service life.
