Three-winding power transformers with РПН, type ТДТН-16000÷63000/150-У1(УХЛ1)

Three-phase, three-winding power transformer with natural circulation of oil and forced air circulation, with voltage regulation under load (РПН) and off-load tap changer (ПБВ). Automatic control is performed via an automatic controller supplied together with the transformer. Using a ТДТН-type transformer ensures reliable power supply to the consumer throughout the entire service life.
