Summary
        FZW □ - 40.5/1250-25 outdoor high-voltage isolation vacuum load switching (hereinafter referred to as load switch) is a new generation of high-voltage electrical products developed by our company and first produced by our company. After strict type test and long-term test run assessment, all technical performance indicators meet gb3804 and IE standards, which are applicable In the power supply network with rated voltage of 40.5kV and rated frequency of 50Hz, the load current can be disconnected, and the capacitance current of overhead lines, cable lines and capacitor banks with a certain distance can also be disconnected. It has the functions of segmentation, isolation, connection and switching, and is suitable for urban power grid, rural power grid, railway, petrochemical and other overhead power distribution lines. The load switch has the advantages of large breaking capacity, safety and reliability, long electrical life, frequent operation and less maintenance.
