It is a kind of metal insulation-enclosed switchgear with vacuum load switch or sulfur hexafluoride load switch (or pressure-operated load switch). It is a new generation high voltage electric equipment, applicable for construction or renovation of urban and rural power grids. This series of switchgear is oil-free and non-toxic, with beautiful exterior, reliable anti-misoperation mechanical interlock, small volume, light weight and easy operation. It realizes both manual and power-driven opening and closing, which guarantees safe use, convenient maintenance and reliable and stable quality. Furthermore, it can be installed against the wall because of its small volume.
