GN22-12 (C) (D) series indoor high-voltage disconnector high-voltage switchgear is used in power systems with rated voltage of 12kV, 50Hz and below, to connect, disconnect or convert lines under voltage but no load.
Matching mechanism: Equipped with CS6-1, CS6-2 and other manual operating mechanisms, and electric operating mechanisms can also be used.
This series of switches are operated by CS6-2 manual operating mechanism or electric operating mechanism, and can be installed on the left or right side of the disconnector.
Structural features
This product is a high-current isolating switch with a three-phase common bottom knife structure. It adopts a mechanical locking prototype with a two-step action of closing and contacting, achieving wear-free contact, small operating force, high contact pressure, and good dynamic thermal stability.
