YB series Compact Substation
Description:
YB series substation is a kind of
compact power distribution device
that integrates high voltage electrical equipment, transformer, and low voltage electrical equipment.
It can be used in
high-rise buildings, building in urban and rural areas, residential communities, high-tech development areas, small and medium-size factories.
mining areas, oil fields, temporary construction sites
, and other premises.
It also can be used for acceptance and distribution of power in the power distribution systems of
6-15KV, 50HZ (60HZ)
, ring main power distribution system, and double power supply or radiate terminal power distribution system.
High integrity, small size, compact structure, safe and reliable operation, convenient maintenance, portable
, etc.
Compared with conventional civil-engineering substations, in the same capacity, the prefabricated combined substation needs only 1/10-1/15 floor area.
So that the
construction expense is reduced
