The FZW32-40.5/1250A-25kA outdoor H.V. isolating vacuum load break switch is an exciting new generation of H.V. equipment developed and manufactured by VACEM electrical co.,ltd. This cutting-edge product meets all the technical performance standards set by GB3804 and IEC. It is specifically designed for the construction and upgrade of urban and rural grids, and is suitable for grids with a rated voltage of 40.5kV and a 3-phase AC 50Hz power supply.
The base of this load break switch is constructed from either stainless steel or pot galvanized carbon steel, with an anti-ultraviolet coating. This ensures that it can operate smoothly and reliably in outdoor environments. All parts of the switch are made from stainless steel, enhancing its durability, stability, waterproofness, and resistance to salt fog. The switch is compact, lightweight, and visually appealing, with user-friendly operation. It boasts high parameters and breaking capability, making it safe and reliable for long-term use. Additionally, it requires minimal servicing and has a long service life. The switch can be operated both electromotive and remotely, providing flexibility and convenience.
