YBM Prefabricated Substation (European box change) is to high-voltage switchgear, distribution transformers and low-voltage distribution devices separated from three different room, via cable or bus to achieve the electrical connection, all the high-low-voltage distribution equipment and transformers are stereotypes of conventional products. Prefabricated Substation Intelligent Series can be high-voltage switchgear (RM6 or GA electrical switch with a remote automatic control device), transformers, low voltage power distribution equipment, low-voltage smart switch, automatic reactive power compensation, according to a certain combination of one cable program to with local or remote operation to reach the remote control, telemetry, remote in terms of features such as remote transfer. Applied to the rated voltage of 12KV and below rated frequency of 50HZ three-phase AC system, and the following 1000KVA capacity in the public distribution network, and terminal loop-powered residential quarters, factories and mines, large construction sites, high-rise buildings, airport terminals and the use of temporary facilities.
