Product Description

Factory YB Customized Prefabricated Electrical Power Distribution

Substation Kiosk Outdoor Substation


Product Features


1. YB box-type series prefabricated box-type substation is used for 6-24KV 50HZ distribution

system to act as a small capacity independent substation. When acting as 6-24 / 0.4KV

step-down station, the general capacity of it is below 1250KV, which is suitable for factories,

mines, ports, stations, residential quarters and underground facilities and other places.

It has advantages of small area and flexible movement, which can go deep into the load center

and adjust the radius of power supply and save energy. So it is popular with users.


2. The optional components of high pressure part include Schneider SM6 / SC6 / ABB's

SafeRing, vacuum circuit breaker cabinets and vacuum load switchgear. High pressure part

can be big or small size, even be a switching station.

3. Low pressure part can be divided into panel type, fixed type and drawer type.

Product composition


Fully sealed and fully insulated structure, no insulation distance required, reliable guarantee

of personal safety;With the characteristics of small size and compact structure, YBP type

pre-installed substation is onlyAbout 1/3, the YBM prefabricated substation is only about 1/2

of the European-style substation with the same capacity;
Can be used for ring network and terminal power supply mode, the conversion is flexible and

convenient;Double-fuse full-range protection method, greatly reducing operating costs;
The cabinet adopts anti-corrosion design and special spray paint treatment, which is suitable

for various harsh environments;Adopt Dyn11 connection method, which has the advantages

of no drift of neutral point and good lightning protection performance;
Perfect transformer design, with the advantages of low noise and low loss;
Serialized products, which can meet the needs of users to the greatest extent;

Communication interface can be reserved to facilitate the expansion of power distribution

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.
