This SF6 load break switch, an switchgear with the rated voltage of 12kV/24kV/36kV, 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 characteistic in its small volume, its convenient for installation and operation and its the great adaptability with surroundings.
The SF6 load break switch and RLS-24D 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.
The SF6 load break switch and RLS-24D load switch plus fuse combination
Note: For short circuit breaking and peak current isbased on Fuseplus combination.
