LW36-40.5 outdoor self energy HV AC SF6
circuit breaker is an outdoor three phase HV AC equipment used in electricity
grids with altitudes of no greater then 3000m, environment termperature of no
less then -30oC, local pollution classes of no higher than Class IV, and AC 50Hz
with maximum voltage of 40.5kV. It is suitable for the control and protection of
HV supply and tranformation lines in power plants, transformer, stations, and
industrial and mining enterprise. It can also be used as a connection circuit
breaker.
LW36-40.5 self energy HV SF6 circuit breaker is equipped with
advanced hot-expansion plus auxiliary pressure gas self-energy arc extinguishing
technology and matched with new type spring actuating mechanism. It has features
such as long electrical endurance, small operating power, high electrical and
mechanical reliability, high technical parameters, and moderate price. It is the
first choice product for current 40.5kV electircity grids.
