Buried substation

With the acceleration of urban and rural modernization construction, urban construction has entered the urban beauty stage aimed at improving the street view and appearance. Traditional box type substations come in different sizes and occupy the prime areas of the bustling city, which is out of place with the beautiful urban environment. With the continuous popularization of the concept of ecological cities, the underground installation of transformers and the transformation of outdoor switchgear into advertising light box style underground box transformers have emerged. Due to its small footprint and ability to coordinate with the surrounding environment, it is widely used in three-phase four wire or three-phase five wire AC power systems with a rated voltage of 380V and a frequency of 50Hz in urban transportation arteries, residential communities, airports, stations, highways, and other places, as an electrical equipment for energy reception, transmission, and control protection.

Buried box transformer is a new type of complete electrical equipment designed and developed to meet the requirements of the above fields. It consists of two parts: buried transformer and outdoor complete switchgear in the form of advertising light box. Buried transformer is a new type of compact power equipment composed of a transformer, high-voltage load switch, fuse, etc. It is installed in a pit, does not occupy surface space, and can operate submerged in water for a period of time. The advertising lightbox outdoor switchgear is a complete set of equipment that integrates advertising billboards and outdoor switchgear. It is installed on the ground, with outdoor high and low voltage distribution cabinets inside the box and advertising lightboxes on both sides, which have excellent visual effects.

Product features

1、 High reliability

The buried transformer box selected for the buried box substation is fully sealed, and the high and low voltage incoming and outgoing lines adopt a waterproof, fully sealed, fully insulated, and fully shielded wiring method.

Waterproofing and drainage considerations were taken into account in the design and production of the transformer pit foundation. The top ventilation hole has effective rainproof and waterproof functions, and the sides and bottom are treated with special waterproof materials to prevent water infiltration. A submersible pump controlled by an automatic drainage system is installed at the bottom

2、 Energy saving and consumption reduction

Energy conservation and consumption reduction have become a consensus in the whole society. The buried box transformer adopts the S11 series of low loss buried transformer products. Compared with ordinary transformers, the no-load loss is 30% lower and the load loss is 15% lower. If a buried transformer with amorphous alloy iron core is used, its no-load loss decreases by 80%.

3、 Reduce noise

4、 Aesthetics, coordinated with the environment

5、 Creating value for customers
