Product Description

General:
GSC-12 an indoor high-voltage SF6 load switch, an switchgear wi ththe rated voltage of  12kV/24kV, adopted with SF6 gas as an arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off andto-ground, and is characteristic in its small volume, its convenient installation and operation and itsthe great adaptability with surroundings. 
GSC-12 of an indoor high-voltage SF6 load switch and   GSC-12D of SF6 load switch plus fuse combination canfunctionto 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. 
GSC-12 of an indoor high-voltage SF6 load switch and   GSC-12D load switch plus fuse combination are complied withthe standards of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc..
