Specifications
General
LW36-126/T3150-40 HV AC SF6
circuit breaker is an outdoor product. It is used inelectricity grids with
altitudes of no more than 2000m (product designs for 3000m are available),
environment temperauteres of no less than -30oC, local pollution classes of no
more than Class iV, and maximum voltage of 126kV to cut off rated currents,
fault currents, or switching lines in order to implement control and protection
of electricity systems. It can also be used as a connection circuit
breaker.
