Prefabricated Electrical Substation Box 4000A Rated Current For Power
Distribution
Features
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.
Advantages
Reduced electrical losses as USS can be installed near load
centres.
Total economy in cost.
Higher degree of safety and operational reliability is achieved by
HT and LT switchgears and protective relays to avoid overloading.
Reduction in logistic cost as USS is delivered as a single unit.
Low civil / foundation cost.

Applications
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.
Service Centre
The shell of the box is made of aluminum-coated zinc steel plate
and container manufacturing
technology, and the design is beautiful. On the premise of ensuring
the reliability of power supply,
the shell color of the box-type substation is selected, so that it
is easy to be in harmony with the
surrounding environment Especially suitable for urban construction.
Such as: Urban residential
areas, stations, ports, airports, parks, green belt and other
densely populated areas, it can be
used as a fixed substation, can also be used as a mobile
substation, with decorative and
beautifying the environment.
