Product Features:
♦ The iron core is made of cold-rolled grain-oriented silicon steel sheets with 45° fully mitred seams, no central holes and an epoxy banding structure. The surface of the iron core is coated with iron core protective paint, which reduces losses and noise;
♦ A new oil channel structure is used, which has high heat dissipation efficiency, reduces the temperature rise of the transformer and extends its service life;
♦ The box is fully sealed with a corrugated oil tank to prevent air and moisture from contacting the transformer oil, reducing oil aging and extending the transformer’s service life. The volume change of the transformer oil due to thermal expansion and contraction is adjusted by the elastic deformation of the corrugated sheet.
♦ The transformer is equipped with a pressure relief safety protection. When the transformer fails and the pressure becomes too high, it can be reliably and safely released through the pressure relief valve to prevent the accident from expanding.
