Product introduction

This series of substation is developed based on the actual situation in China. The transformer is S11 series. Four-position load switch, two-position load switch, backup protection fuse and plug-in fuse are installed on the high voltage side. Controlling appliance, power distribution appliance, compensation device and electric energy meter are installed on the low voltage side. The transformer oil takes the role of insulation and arc-extinguishing medium. The overall substation features small volume, easy maintenance, low noise, low loss, theft prevention, high overload capacity and all-round protection. It is suitable for new-built residence communities, green belts, gardens, bus stations, wharves, hotels, construction sites and airports.
