Underground transformer is a type of transformer installed on an outdoor base without direct contact with the public and capable of operating submerged in water for a certain period of time. Buried transformers have the function of power transformation and distribution, which can replace traditional substations and be widely used in industrial parks and residential communities.

With the development of cities and the deepening of urban power grid transformation, safe, reliable and non occupying underground transformers are gradually applied to road lighting, residential electricity, airport, city square, expressway, bridge, tunnel lighting, etc. in central urban areas.

Usage conditions:

◆ Altitude not exceeding 1000m

◆ Maximum ambient temperature+40 ℃

◆ Maximum daily average temperature+30 ℃

◆ Maximum annual average temperature+20 ℃

◆ Minimum temperature -25 ℃

Product features:

◆ Immersion operation: IP68 protection level, stable immersion operation.

◆ Safety+: fully sealed, fully insulated, and fully shielded wiring method, with fuse protection on the high-voltage side.

◆ Good energy-saving effect: Adopting high conductivity silicon steel sheets or amorphous alloy iron cores greatly reduces the white body loss of transformers

◆ Maintenance free and long service life: a combination of 2.5MM thick high-strength steel plate seamless welding and corrosion-resistant process treatment
