Ruhi Unitised Substation

RANGE: Up to 2000 KVA in 11 KV line voltage

Ruhi Electronics offers a qualitative range of PSS (Package Substation) or USS (Unitized Substation) Transformer from 200 KVA to 2000 KVA in 11 KV Class. These Package Substations are largely required for fire hazardous and compact places. A unitized substation is a compact arrangement, which simplifies conventional substation design. Substation housing is divided into three compartments i.e. the HV Compartment, the Transformer Compartment and the LV Compartment.
