Prefabricated substation · European-type
YB Prefabricated Substation (European-Type)
YB-12 (40.5) series
Transformer, HV and LV switchgear in one enclosure, for public buildings, industry, transport and new energy.
- Rated capacity
- 200–8000kVA
- High voltage
- 7.2–40.5kV
- Protection
- up to IP65
Overview
The YB prefabricated substation installs the transformer, high-voltage switchgear, low-voltage switchgear and other switchgear in the box-type housing, with LV metering, compensation and auxiliary power as needed.
Widely used in power systems, public and high-rise buildings, stadiums, industrial and mining enterprises, traffic stations and new-energy PV and wind generation; serves as a permanent installation or construction-site supply, for ring-network or terminal distribution with cable transmission.
