High quality safety vcb ZW32-12D/630-20 series pillar type outdoor
high-voltage
12kv vacuum circuit breaker
ZW32-12 series pillar type outdoor vacuum high-voltage circuit
breaker is a kind of outdoor
high-voltage switch equipment of three phase frequency 50HZ,rated
voltage 12kv.It is used
in opening and closing the load current, overload current and short
circuit current of the power
distribution network of the whole city or the village.
Service conditions:
a. ambient air temperature , upper limit +40, lower limit-40
b. elevation,≤1000mIf there is any need to increase the elevation,,
the rated insulation level
should be increased properly
c. wind pressure, less than 700pa(the same as 34m/s wind speed)
d. Amplitude, The earthquake intensity does not exceed 8 degrees
e. pollution level, level 3
f. daily range of temperature ,less than 25
