Electric SF6 3150A Overvoltage Protection 145KV VCB Circuit Breaker
Overview
LW36-126(145)(W)/T3150-40 self-contained power HV AC sulfur hexafluoride circuit breaker is an outdoor product. It is used in electricity grids with altitudes of no more than 2000m (product designs for 3000m are available), environment temperatures of no less than -30℃ (low-temperature products are suitable for -50℃~+40℃), local pollution classes of no more than Class IV, and maximum voltage of 126/145kV 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.
