European box transformer
Description:
European box substation is a high-voltage switch set, distribution transformer and low-voltage distribution device in three different compartments, and electrical connections are realized through cables or busbars. The high- and low-voltage distribution devices and transformers used are Regular styling products. The intelligent prefabricated substation series can combine high-voltage switchgear (RM6 or SFG, domestic load switches with electric remote automatic control devices), transformers, low-voltage distribution settings, low-voltage smart switches, and automatic reactive power compensation according to a certain wiring plan Integrated into one, it has the functions of remote control, telemetry, telemetry, remote adjustment and other functions for local or remote operation.

YBM prefabricated substation (European box transformer)
European box substation is a high-voltage switch set, distribution transformer and low-voltage distribution device in three different compartments, and electrical connections are realized through cables or busbars. The high- and low-voltage distribution devices and transformers used are Regular styling products. The intelligent prefabricated substation series can combine high-voltage switchgear (RM6 or SFG, domestic load switches with electric remote automatic control devices), transformers, low-voltage distribution settings, low-voltage smart switches, and automatic reactive power compensation according to a certain wiring plan Integrated into one, it has the functions of remote control, telemetry, telemetry, remote adjustment and other functions for local or remote operation. It is suitable for public distribution networks with rated voltage of 24KV and below, rated frequency of 50Hz three-phase AC system and capacity of 2500kVA and below, residential communities, factories and mines, large construction sites, high-rise buildings, airport terminals and other areas with ring network and terminal power supply. Temporary facilities, etc.
