APPLICATION The GK Pole Mounted Remote Controlled SF6 Gas load Break Switch is designed for distribution automation system which typically requires a significant increase in the amount of load - Break operations performed. GK Switches are available for cross arm mounting and is applicable to 24kV and 36kV overhead distribution system.
2 It can be operated electrically (from local control panel or from remote location) and manually. FEATURE SF6 Gas insulation and interruption Stainless steel permanently-sealed enclosure ,no need of maintenance Simple and strong toggle mechanism Safety feature with low pressure safety locking device, over pressure releasing Build-in current sensors to measure current at +/- 3% accuracy PRODUCT DETAILS Type Model GK-GS2406 GK-GS3606 Rated system voltage 24KV 36kV Rated current 630A 400A Rated frequency 50/60Hz Rated short-time current (1 sec, ) 10kA Rated short-circuit making current(peak) 25kA Power frequency withstand voltage 60/70kV Lightning impulse withstand voltage 150/170kV Number of no- load switching 2000 times Number of load switching 400 times Rated control voltage DC24V(or AC110/220V)
