Product Description

PRODUCT DESCRIPTION

General
GSC an indoor high-voltage SF6 load switch, a switchgear with the 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 and to-ground, and is characteristic in its small volume, its convenient installation and operation and its the great adaptability with surroundings.
GSC of an indoor high-voltage SF6 load switch and GSC of 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.
GSC of an indoor high-voltage SF6 load switch and GSC load break switch plus fuse combination are complied with the standards of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc..
