High Degree Safety Electrical Substation Box Unitized Substation Transformer

 

Hengfengyou offers 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.

 

1  Reduced electrical losses as USS can be installed near load centres.

2  Total economy in cost.

3  Higher degree of safety and operational reliability is achieved by HT and LT switchgears and protective relays to avoid overloading.

4  Reduction in logistic cost as USS is delivered as a single unit.

5  Low civil / foundation cost.
