combined HV eletrical equipment, transformer and LV equipement to form a set of distribution substation.
Combined Transformer Substation
1. Combined transformer substation is the power distribution equipment combining HV electrical equipment, transformer and LV equipment that is used for city tall building, urban &rural building, residence communities, medium & small factories, mines, oil fields and temporary electrical power construction site. The station’s function is to receive and distribute power energy in power distribution system.
2. Combined transformer substation features compact structure, package unit, safe and reliable operation, convenient maintenance, attractive appearance, high mobility and small size. It can be used as loop net work power distribution system, and also as double-power or radiating terminal power distribution system. It is a new set of equipment for urban & rural transformer substation construction and renovation.
