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.
