Dry-type transformers from 25 to 2500 kVA are used to step down three-phase voltage of 6 or 10 kV to a lower 0.4 or 0.23 of frequency 50Hz for industrial installations and package transformer substations.
Dry-type transformers are used in industrial and urban uses to minimize hazard and other environmental contamination
Dry-type transformers are used when operating safety, fire resistance, environmental friendly technology and small dimensions are required as liquid-filled types
We offer a full range of dry-type transformers with vacuum cast resin, forced cooling with pumps and funs, in protective housing
Conforms to GOST 11677-85 “Power Transformers. General Application”, GOST 27050-86 “Power transformers size I-III (capacities from 5 to 6300 kVA inclusive, voltage up to 35 kV)”
