European type substation consists of high voltage chamber, transformer chamber and low voltage chamber. A High side voltage is generally equipped with annular net cabinet (which can be equipped with production gas, pressed gas vacuum, SF6 loading switch and fuse protection), and also equipped with vacuum, SF6 fuse, with features of being smaller in volume, safe and reliable. A Either S11-M.R, S9-M.R oil immersed transformer or SC9,SG10-R dry type transformer is used for the transformer. A The new type of intelligent fuse and plastic shell air switch are used for low voltage side, which has the features of being high disjunction and good protection performance. A The outside shell is made of aluminum allay, high quality steel plate, compound plate etc, the top cover is made in two layers to prevent heat radiation efficiently. A There are automatic winds discharge system and condensation proof device in the transformer body.
