1.Structure features
YB series prefabricated substation is composed of high voltage power distribution equipment, transformer and low voltage power distribution equipment, divided into three functional compartments, which are high voltage room, transformer room and low voltage room.
2. Enclosure types
General substation which is made of ordinary steel plate
High anti-corrosion type substation which is made of stainless steel or aluminum alloy plate
Heat preservation and insulation type substation which is made of colored composite plate
Other kinds of substations
3. Layout types
YB series prefabricated substation types:
YB series prefabricated substation have two arrangements, "mu" type (YBM) "pin" type (YBP)
----- "mu" type
------- "pin" type
