Disconnect Switches
Horizontal and Vertical Design Configurations up to 800kV

Flexible design configurations supporting ANSI and IEC technical specifications, as well as specific insulator requirements.


GW4
GW4 - Center Break

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
GW7 – Double End Break

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 earthing switch and the main blade to ensure a correct operating sequence of the disconnector and earthing switch.

GW10
GW10 - Vertical Pantograph

The main blade of the GW10 series disconnect switch is a pantograph blade with an insulated single break in the vertical direction at the open position with minimum clearance between phases and vertical length.

GW11
GW11 – Horizontal Pantograph

The main blade of the GW11 series disconnect switch is a pantograph blade with an insulated single break in the horizontal direction at the open position with minimum clearance between phases and vertical length.

GW6
GW6 - Double Arm Vertical Pantograph

The main blade of the GW6 series disconnect switch is a pantograph blade with an insulated single break in the vertical direction at the open position with minimum clearance between phases and vertical length.
