This product is based on the technology of LW36A/B-72.5/126/145, developed
by Xi'an HV Electrical Apparatus Institute and HEAG group. It absorbs experiences
and technics in similar product manufacturing and perfected as a new generation
of self-evolving SF6 HV circuit breaker. LW36A/B-72.5/126/145 is used to control
and protect circuit in 72.5/126/145kV and AC 50/60Hz power system. It is SF6
insulation with CT30 spring operation mechanism.
