1.General description

FZW32-12/T630-20 outdoor H.V. isolating vacuum load break switch, a new generation of H.V. electrical equipment jointly developed by Weicheng electrical co.,ltd. with techniques of xi' an High-voltage Electrical Equipment Research Institute and firstly manufactured by our company, has passed the strict type test long-term test.All of its technical performance indexes have been up to the standard of GB3804 and IEC. The product is designed mainly for building and upgrading urban and rural grid and is applicable for the grid with rated voltage of 12kV, 3-phase AC 50Hz.

Its base is made of stainless steel or pot galvanized carbon steel with anti-ultraviolet coating, which ensures that is can run smoothly outdoors. All of its parts are made of stainless steel to improve the durability, stability, waterproofness, and salt fog resistance of the load switch. It is entitled to compactness,light weight, handsome figure, operation friendly, high parameters and breaking capability, safe and reliable, long service life, can be operated frequently, requires less servicing, and has evident fracture. It can be operated manually with a single pole,or electric remote control.
