      SF6 Air insulated switchgear GSM Modular Units up to 36kV

      Secondary distribution products--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.
