Product Description

Product Description

++++General
GSC is an indoor high-voltage SF6 load break switch, for switchgear with the rated voltage of 12kV/24kV, adopted  SF6 gas as arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off and to-ground, and is characteristic in its small volume, its convenient installation and operation and its the great adaptability with surroundings.
GSC is an indoor high-voltage SF6 load switch and GSC-SQC SF6 load switch plus fuse combination can function to protect and control the electric equipments for power supply and transformer substations especially being suitable for ring net cabinet, cable branch cabinet and distribution switching substation.
Complied with the standards of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc..
