35kV step-up transformer

The winding of the 35kV step-up transformer adopts high conductivity copper conductors, and the high and low voltage are all copper windings. The iron core is made of high-quality domestic high magnetic orientation silicon steel sheets. The iron core is firmly tied and clamped, with good insulation. All fasteners are treated with anti loosening, and the transformer body adopts a new insulation structure. The transformer has strong short-circuit resistance. The transformer is equipped with a temperature controller, which not only displays the temperature of the three-phase winding during operation, but also has control functions such as fault alarm, high temperature sound and light alarm, and over temperature trip alarm. The product is equipped with a fan, which can effectively protect the safe operation of the transformer.
