product description
YB box-type substation is mainly composed of multi-circuit high-voltage switching system, armored busbar, substation comprehensive automation system, communication, telecontrol, metering, capacitance compensation and DC power supply and other electrical units. It is installed in a moisture-proof, rust-proof, dust-proof , rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, movable steel structure box, mechanical and electrical integration, fully enclosed operation. It has the advantages of high degree of automation, safe and reliable operation, simple maintenance, convenient movement, and beautiful appearance. The product shell has an IP33-IP66 protection level.
The main purpose
YB prefabricated box-type substation is widely used in industrial and civil cable ring networks and power supply terminal projects. It is used in urban power grid transformation, residential areas, high-rise buildings, industries and mines, hotels, shopping malls, airports, railways, oil fields, docks, highways and temporary power facilities and other indoor and outdoor places to receive and distribute electric energy in the power distribution system.
