35kV step-up transformer

35kV step-up transformer winding adopts high conductivity copper conductor, high and low voltage are all copper windings. The iron core adopts domestic high-quality high-permeability oriented silicon steel sheet, the iron core is firmly bound and clamped, and has good insulation. All fasteners are treated with anti-loosening. The transformer body adopts a new insulation structure, and the transformer has strong short-circuit resistance. The transformer is equipped with a temperature controller. In addition to displaying the three-phase winding temperature during operation, it also has control functions such as fault alarm, high temperature sound and light alarm, and overtemperature trip alarm. The product is equipped with a fan, which can effectively protect the safe operation of the transformer.
