SF6 gas is adopted as insulating and arcing medium. The arcing mode is constant magnetic field rotating arc, so its arcing ability will not be affected by magnitude of arc and current. Besides, it has good breaking capacity, small over-voltage, long electrical life and maintenance-free arc extinguish chamber. -Advanced GSC series (SIC and SQC type) indoor SF6 load break switch and composite apparatus are adopted. It has three positions:"closed", "open", "earthed".
