Product Description

ZBW(YB)17-10 Series     HV/LV Prefabricated (American type)Substation



The combined American box change is a transformer body, high voltage load switch, fuse and other components.
It is placed in the transformer oil tank. Because it is immersed in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible. Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance free. Widely used in residential quarters, high-tech centers, factories and mines, airports, stations, schools.

Main features:

Overload capacity strong,allowing overload 2 times 2hours,overload 1.6 times 7 hours without affecting the life of the box change.Adopt elbow plug connector,high-voltage cable can be very convenient joint into the connection,and in emergency situations as a load switch to use,can live plug.

Double-fuse protection,plug-in fuse(BAY-o-net) for the double-sensitive fuse (temperature,current) protection box secondary side of the short-circuit failure occurred.

The back-up current limiting fuse(ELSP) protects the cabinet from internal faults and protects the high-voltage side.


Normal conditions of use

Altitude: not exceed 1000m;
Ambient temperature:-35oC~+40oC
Relative humidity: daily average of not more than 95%, on average less than 90%;
Installation place: no fire, explosion, chemical corrosive gas and well-ventilated place, the ground angle of not more than 3°.


Product Features

1.Compact structure, small size, convenient installation and flexibility;
2.Fully insulated, fully sealed structure, safe and reliable, maintenance-free, and reliable protection of personal safety;
3.The high-voltage side is protected by a double fuse, wherein the fuse of the plug-in fuse is a double-sensitive fuse (temperature, current), and the backup fuse is a current-limiting fuse, which reduces the running cost;

4.high-voltage incoming line adopts cable connector structure, fully insulated, safe and reliable, and easy to operate;
5.can be used for both ring and terminal, conversion is very convenient, and the reliability of power supply is improved.

6.The transformer is a three-phase three-column or three-phase five-column structure. The iron core adopts a step joint process or a coil core process, which has low noise, low loss, short circuit resistance and strong overload capability.

7Using the special process of vacuum drying and vacuum oiling, our company will extend this process to 110kV products to 10kV products, which provides a strong guarantee for improving product quality.

8. The cabinet can be treated with anti-corrosion design and special paint treatment according to the requirements of the operating environment. It has the functions of “three preventions”, namely anti-condensation, anti-salt spray and anti-fungal, and can meet the anti-corrosion requirements under high temperature and high humidity environment.

General requirements:

1.Simple lighting,public power distribution,the case into the high-voltage wiring scheme does not need to set high-pressure measurement,only low-pressure measurement or no measurement,no compensation.Feeding circuit 4-6 back,the use of plastic circuit breaker control and protection.

2.Power lighting,public power distribution,the box transformer with a change in the circuit has increased to 8 to 12 back,in addition,there should be reactive power compensation.

3.Box-type transformer substation covers small footprints,General box-type transformer substation covers an area of only 5 to 6 square meters,or even reduce the 3 to 3.5 square meters.Suitable for general load-inensive industrial and mining enterprises,ports and residential quarters and other places,can be extended.
