Oil-immersed transformers

Oil-immersed transformers

We produce three phase oil-immersed distribution transformers with rated power in range from 25 kVA up to 25,000 kVA. 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. We produce oil-immersed transformers with different series of losses according to EN 50464-1 but also special transformers for dedicated services with customized losses and design.
