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.

America type box transformer characteristics:

1.Compact structure,small size,easy installation and flexiable;

2.Fully insulated,fully sealed structure,safe,reliable,maintenance-free,reliable protection of personal safety

3.High-voltage side use of dual-fuse protection,which plug-in fuse for the unika fuse(temperature, current),back-up fuse for the current limiting fuse,reduced operating costs;

4.High-voltage cable use of cable connector structure,whole insulation,safe,reliable,easy to operate.

5.Can be used for ring network,also for the terminal,the conversion is very convenient and improved the reliability of power supply.

6.Transformer for the three-phase three-column or three-phase five-column structure,the core used ladder joint process or roll core echnology,low noise,low loss,anti-short circuit and overload capacity.

7.Adopt of the special process vacuum drying and vacuum oiling,use in the 110KV products of this process extends to 10KV products,provide effective protection to improve product quality.

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.



Below are the tests conducted by Varelen before delivery. Other tests required by clients can also be done accordingly.

Insulation resistance

Resistance of all windings

Check voltage ratio and vector group

No-load test at rated frequency and rated voltage

Impedance test

Withstand voltage test

Induced over-voltage withstand test

Partial discharge measurement


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.
