European Prefabricated Outdoor Transformer Box Substation

Short Description:


YB series European Prefabricated outdoor transformer box substation is used new technology and advanced components as well as high low voltage automation technology, the high voltage 12KVcan meeting the demand of power department for power distribution automation and the low voltage 0.4KV can meet the demand of intelligent community property management. And the upper monitor which is located in the central station or the property management department can be used for four-remote system management. When several intelligent box substations connect into “hand-in -hand” ring network and supply power combined with autonomous software can accomplish the functions of automatic location. Fault clearance. Load shifting and network reconfiguration at the fault section. So that the recovery of power transmisson is guaranteed in one minute.
