What is an underground transformer?

Underground transformers are equipment used for voltage transformation. This device is divided into two parts: above ground and underground, suitable for urban environments (installed in basements or cellars), especially for densely populated central cities. The ground mounted diversity billboard and low-voltage switch box are integrated, and the body adopts a stainless steel fully sealed structure, equipped with a waterproof concrete base and drainage system, which can achieve safe operation in the pit.

 

technical feature
1. Suitable for urban environments (installed in basements or cellars), especially for densely populated central cities
2. Lighting and power systems suitable for streets, highways, bridges, tunnels, parking lots, airports, ports, tourist attractions, etc
3. The high and low voltage incoming and outgoing lines adopt a waterproof, fully sealed, fully insulated, and fully shielded wiring method
4. The outer shell of the box is made of anti-corrosion stainless steel, fully sealed, and can be immersed in water for a period of time
5. Using an operating rod to operate a buried transformer, it has the same operating mode as a combination transformer
6. Fully considering the particularity of heat dissipation conditions, the transformer adopts a low loss and low temperature design;
