Product Description

substation prefabricated electric compact substation box type transformer


product description


The light box type underground box substation is mainly composed of an underground transformer (including a prefabricated pit) installed underground and an outdoor advertising light box type high-voltage switchgear installed on the ground. Among them, the underground transformer is a new type of distribution transformer with high-voltage fuse protection and can be submerged in water for a period of time. It has been widely used in airports, highways, bridges, tunnels and other places in my country. ; The interior of the outdoor light box type high and low voltage switchgear is an outdoor high and low voltage distribution cabinet, and the outside of the box is an advertising light box. The content of the poster can be designed according to the surrounding environment and user requirements. The entire product occupies a small area, is beautiful and generous, not only can be highly coordinated with the surrounding environment, but also can achieve the role of advertising.
