FZW32-24 type outdoor high voltage isolating vacuum break load switch is a new type of load switch which is the integration of mature experience of domestic existing load switch and advanced technology design of external. This load break switch is composed of disconnector, vacuum interrupter and operating mechanism and other parts. By using the principle of vacuum interrupter, with strong arcing ability, reliable performance, long service life, small volume, no explosion danger, no pollution etc advantage. The product can be used in transmission and distribution system of electric power, metallurgy, mine, chemical industry and other departments as control equipment, especially suitable for frequent operation place.
