Outdoor Combined Power Transformer Substation

Combined Power Transformer Substation

YB-12 Type outdoor box type substation, also called pre-assembled substation is a kind of distribution equipment made up of high voltage equipment, distribution transformer, low voltage distribution system and auxiliary equipment. It is installed in a moisture proof, dust proof, antirust, full sealed and removable steal type box and used under rated voltage of 10/0.4V three phase AC system as a receiver, transformer and distributor in electric system. It is very adaptable for city building and reforming, such as city public distribution system, high building, residential quarters, port, oil field, wind generating substation, enterprise, park and high speed road and so on.

YB-12 type outdoor substation has 10kV high voltage compact solid insulated switchgear, and technically has compact, small volume, environmental friendly, maintenance free, high reliability, high automation functions and so on. It is able to satisfy city electricity demands, and financially occupies small land, low invest and removable functions.
