We produce three phase oil-immersed distribution transformers with rated power in range from 25 kVA up to 5MVA. Our transformers are both types, hermetically sealed and with conservator. They are manufactured in accordance with local and international standards and fully adapted for mounting in complete transformer substations and steel-lattice poles. The windings can be made from aluminium or copper depending on customer requirements and needs.
