Prefabricated Electrical Substation Box 4000A Rated Current For Power Distribution
Overview
YB20 Pre-install European box-type transformer substation ,which
includes high-Voltage Switchgear , transformer and low-Voltage
Switchgear,which features are beautiful appearance, flexible
configuration, compact structure,can be mached with the high
voltage load switch ,also can match with the Intelligent interface
, that achieves four remote control system,that is the best choice
for the the city power grid, landscape area, square, Garden and
residential area .
Power transformer substation
*Features:
-Including independent high voltage room, transformer room and the
low pressure room;
High voltage wiring can be used for ring network, terminal and dual
power supply, flexible power supply, high reliability;
-Transformer can be used dry type or oil immersed type transformer,
transformer performance is excellent: low consumption loss, low
noise, low temperature rising, high overload capacity, anti-short
circuit ability, strong impact resistance;
-The low pressure room has the overall function of the complete set
of low voltage equipments.

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.
