ZW32-12 Outdoor
High Voltage AC Vacuum Circuit Breaker
General
ZW32 Outdoor High Voltage AC Vacuum Circuit Breaker (hereinafter
called breaker) is a new generation outdoor vacuum circuit breaker
researched and developed recently based on the foreign advanced
technology and combining the features of power industry of our
country.
The breaker is an outdoor high voltage switch equipment of 3-phase
,50Hz .rated voltage 12kV, mainly used in the distribution system of
urban network .rural network, substation, industrial and mineral
enterprises for cutting load current .overload current and short circuit
current. Due to the special feature of vacuum circuit breaker, it is
particularly suitable for the sites where frequent operations and no
oiling are required.
The breaker complies with the standards of GB 1984 "AC High
Voltage Breaker", JB3855 "3.6^t0.5kV Indoor AC High Voltage Vacuum
Circuit Breaker" and as well as the relevant requirements of IEC.
