SF6 Air insulated switchgear GSM Modular Units up to 36kV
Using SF6 gas as insulation and arc extinguishing medium, rotating arc and
arc extinguishing of a constant magnetic field make the arc esxtinguishing capability
free from the influence by the arc current,pefect breaking performance,weak overvoltage,
long electrica life span, arc chamber maintenance-free.
High quality GSC series (SC6-SIC type, SC6-SQC type) Indoor SF6 LBS, composite apparatus.
Three-position, multi-functions; easy operation, high reliability operation mechanism and lock,
with a small gas pressure gauge. Passed SF6 gas zero pressure rated breaking test,
super functional , high reliability.Earthing switch has the short-circuit making capability
which corresponds to national standard.
