GW4 Disconnect Switches Center Break Disconnect Switch GW4 series disconnect switches are structured in double columns for single pole, one break, and horizontal rotary opening. There are two columns in each phase. Supporting insulators at both ends are rotated horizontally by the operating mechanism in performing the open and close operations. The main conductive blade is mounted on the top of the supporting insulator. A mechanical interlock is mounted between the earthing switch and the main blade to ensure a correct operating sequence of the disconnect switch and earthing switch....

GW7 Disconnect Switches Double End Break Disconnect Switch GW7 series disconnect switches are structured in three columns for single pole, double breaks, and horizontal rotary openings. There are three columns in each phase. Supporting insulators at both ends are fixed while the middle one can be rotated horizontally by the operating mechanism in performing the open and close operations. The main conductive blade is mounted on the top of the middle supporting insulator, and the stationary contacts are on the top of the other two fixed contacts. A mechanical interlock is mounted between the...
