Product Details

In order to realize the replacement of American box transformer equipment, on the basis of standard 400kVA, 500kVA and 630kVA European box transformer, the outgoing isolating switch on LV side or main incoming switch on LV side shall be canceled, the compensation capacitor shall not be more than 4, and the compensation capacity shall be reduced to 15% of the rated capacity to form an alternative box transformer substation.

Standardized design of 10kV HV/LV preassembled substation standardized design scheme (version 2023) 29 shall be carried out according to the maximum shape (length × width), transformer capacity 630kVA, ring network scheme, and compatible with transformer capacity 400kVA, 500kVA and terminal scheme. At the same time, the appearance of metal and non-metal material boxes is unified. Based on the above principles, the overall interchangeability of alternative box transformer is realized.
