The 33kv dry type transformer is called an epoxy resin casting transformer and uses epoxy resin as an insulating material. The high and low voltage windings are made of copper strip (foil). The epoxy is cast and cured in a vacuum to form a high strength FRP structure. The insulation get more info grade is F and H. Epoxy dry-type transformer has the characteristics of good electrical performance, strong anti-lightning capability, strong short-circuit resistance and light weight. A temperature display controller can be installed to display and control the operating temperature of the transformer windings to ensure the normal life of the transformer.
