China Best Distribution Box (Plastic Base) Cadb1 Supplier – S-M.D Series Buried Power Transformer – Changan Group Detail:

Product introduction

S □ -M·D series three-phase buried oil immersed transformer produced by the company is a kind of compact power distribution equipment which installs transformer, high-voltage load switch, fuse for protection in the same oil tank. The high-voltage and low-voltage incoming and outgoing lines adopt fully insulated, fully sealed and fully shielded waterproof joints, which do not occupy the surface space, can be immersed in water for a certain period of time, and are maintenance free. It can be widely used in densely populated central city, streets, highways, bridges, tunnels, parking lots, airports, ports, tourist attractions and other power distribution systems, especially for places with strict requirements on height and floor area.
In the product design, the special situation of ventilation and heat dissipation is fully considered, and the design of low loss and low temperature rise is adopted. According to the distribution mode, it can be divided into ring network distribution type and terminal distribution type to meet the different needs of users.
