Overview

10KV outdoor switching station, mainly used in the power supply and distribution system with rated voltage of 12kV and rated frequency of 50Hz, has the function of connecting, transferring and distributing electric energy. The equipment has the advantages of excellent performance, standard design, beautiful appearance, corrosion resistance, small volume, safe and reliable, compact structure, flexible and convenient. It can be operated by electric or manual, and can realize the “three remote” functions of remote control, telemetry and remote signaling, and improve the reliability of power supply. It is widely used in urban power grid reconstruction, residential area, commercial center and other urban densely populated areas.
