SX
Pantograph Disconnector up to 550 kV
The SX is a space saving double scissor aluminium disconnector connecting the lower busbar to the upper one via the pantograph arms. Horizontal rather than vertical separation means a space reduction of as much as 30%.
Customer Benefits
- Clear conducting routing for safety
- Rigid or flex busbars for flexibility
- Double scissor design for high rigidity
- Built-in ground switches available
- Virtually maintenance free
- Easy start-up and commissioning

Pantograph Disconnector up to 550 kV
The SX is a space saving double scissor aluminium disconnector connecting the lower busbar to the upper one via the pantograph arms. Horizontal rather than vertical separation means a space reduction of as much as 30%.
Customer Benefits
- Clear conducting routing for safety
- Rigid or flex busbars for flexibility
- Double scissor design for high rigidity
- Built-in ground switches available
- Virtually maintenance free
- Easy start-up and commissioning
- Rugged performance in adverse conditions including high winds, heavy ice or seismic conditions, stable in closed position during short circuits
- Blades are tubular aluminium with replaceable silver-plated copper contacts
- Galvanized structural steel channel base supports the insulators and live parts, providing high strength and rigid design
- All bearings and counter-balancing springs are isolated from the main path
- Reduction of encumbrance for rated voltage above 300 kV due to special design of bearing frame which allowed the removal of anti-corona rings
- Clear busbar arrangement and routing results in increased safety during operation and maintenance
- Flexible installation and arrangement configurations
- Available Life Cycle Assessment on request
- Available the supply of recycled material to reduce environmental impact on request
