FZW32-12 type outdoor high voltage disconnecting 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.
Instruction
a. Use vacuum interrupter, without explosion hazard and no need maintenance.
b. Disconnector and three-phase vacuum interrupter are ganged, when opening, there is obvious disconnecting fracture.
c. All components use stainless steel material, the chassis uses stainless steel material or hot galvanizing coated with anti UV protection paint carbon steel, ensures product’s normal operation in outdoor environment.
d. Installation way mainly are single pole mounting and manual operation, also use motorized or remote control operation.
e. Widely used in rural and urban distribution network, railway and other distribution electricity circuit retrofit. f. Great breaking capacity, safe, reliable, long electrical life, and can be operated frequently
Environmental Conditions
a. Altitude ≤1000m;
b. Ambient air temperature -30~+40℃;
c. Relative humidity: daily average ≤95%, monthly average ≤90%;
d. Without frequent violent vibration.
