UV Transformer offers qualitative range of PSS (Package Substation) or USS (Unitized Substation) Tranformer from 100 KVA to 2000KVA in11 KV Class. Compact Substation are used for feeding power from high voltage to low voltage. The substation is compact in size, suitable forfrequent shifting and for use in indoor / outddor locations. The substation is A unitized substation is a compact arrangement, which simplifies conventional substation design.
Substation housing is divided into three compartment i.e. the HV Compartment, the Transformer Compartment and the LV Compartment.
| HV Compartment | Transformer Compartment | LV Compartment |
|---|---|---|
| Extendible & Non Extensible MV Switchgear - Ring Main Unit (RMU) | Oil Immersed Transformer / Dry Type Transformer (VPI / Cast Resin) | LV Distribution Board |
| Vacuum / SF6 Circuit Breaker, RMU & HV Fuse | LT Control Panel with incomer ACB & Outgoing MCCB | |
| RMU & Load Break Switch | APFC Panel | |
| Protection & Metering Devices | LV Switch fuse unit | |
| Current & Potential Transformer for Metering / Protection. | Instrumentation and Metering | |
| Illumination Internal Lighting & Door Limit Switches, Tailor made enclosures mounted on the transformer under base to provide single lift complete installation with theft proof design. |
USS(Unitized Sub Stations) / Package Sub Station are ideally suited for new residential and commercial complexes as it can be placed on Ground,partially or totally below / above ground level. Mainly used by Power Utilities, Multiplexes, Hotels, Hospitals, Shopping Malls, Software Parks, Residential Complex, Airport etc.
