GNEE Steel mini substation transformer
The prefabricated compact substation transformer is one kind of compact complete set of distribution equipment which designed combining medium voltage switchgear, low voltage switchgear, distribution transformer, energy metering devices and reactive power compensation devices into one or several boxes according to a certain wiring scheme. It is suitable for three-phase AC systems with a rated voltage of 11KV or 33KV for line and distribution of electrical energy.
With the advantage of compact size, prefabricated compact substation transformer was widely used in the three phases of the power distribution system with the voltage rating from 11kV to 33kV for electricity distributing. The protection degree reached IP55, so it could be installed outdoor by occupying the small area.
Prefabricated compact substations transformer are suitable for residential quarters, urban public utilities and construction power supplies etc., users can select compact transformers according to different conditions of use and load levels.

Prefabricated Substation Transformers Feature
Modular Design:
Prefabricated compact substations transformer are designed with modularity in mind. The various components, such as transformers, switchgear, and control systems, are integrated into a compact and pre-assembled structure.
Transformers:
The substation includes transformers for voltage transformation. The transformers can be designed for different voltage levels, depending on the specific requirements of the electrical distribution system.
Switchgear and Circuit Protection:
PCSTs incorporate switchgear to control the flow of electricity and provide protection against overloads, short circuits, and other electrical faults. Circuit breakers and protective relays are commonly included.
Enclosure:
The substation is enclosed within a weatherproof and secure housing. The enclosure protects the equipment from environmental conditions such as rain, wind, and dust, ensuring the reliability and longevity of the substation.
Compact Size:
The compact design of the substation allows for installation in areas with limited space, making it suitable for urban environments or locations where space constraints are a consideration.
