Preassembled transformer station
I. Introduction to product
YBMWD-12/0.4 series of preassembled transformer station manufactured by this company is a complete set of distribution facility, which integrates high-tension switch gear, transformer, low-tension switch gear into one box as per a certain connection scheme.
This series of preassembled transformer station is used for accepting and distributing electric energy in three-phase alternating current system below rated voltage 12KV, frequency 50HZ and capacity 1250KV. It is not only applicable to public distribution, high-rise building and community, but also industrial and mining establishment, temporary job location of engineering.
