Prefabricated Electrical Substation Box 4000A Rated Current For Power
Distribution
Features
The cabinet shell is designed according to foreign advanced
technology and actual situation, with features of fastness, ventilation and heat insulation,
dust-free, prevent small animals, moisture proof, beautiful design, convenient to maintain. Shell
material has a range of choices: Aluminum sheet, steel sheet, composite board, stainless steel
sheet, nonmetal material
(glass, fiber, cement).
H. V side mainly uses load switch, while vacuum circuit breaker is
also available with complete misoperation function. It also can equip
with XGN20-12L SF6 looped-network cabinet and looped-network switch device such as
HXGNI5A, HXGNI7.
Transformer can be oil immersed, full enclosed and dry-typed.
Substation is with perfect protectionperformance and convenient operation. H&L V metering is
available, it can also
equip withautomatic reactive power compensation devices.

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 only About 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 automation.
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.
