Powering a Greener Future with GRiDEA The SX Pantograph Disconnector is a proud member of the GRiDEA portfolio—GE Vernova’s suite of solutions specifically engineered to accelerate grid decarbonization. By integrating advanced technology with sustainable design principles, we help operators modernize their infrastructure for a digital future. 

Committed to Raw Material Preservation

As part of the second pillar of our GRiDEA framework, the SX disconnector is designed to minimize environmental impact through smarter manufacturing and digital intelligence: 

  • Resource-Efficient Construction: We have significantly reduced raw material consumption, utilizing up to 70% recycled aluminum and saving up to 240 kg of steel, copper and aluminum per 420 kV unit. 

  • Digital-Native Solution: Our integrated smart monitoring shifts maintenance operations from time-based to condition-based. By monitoring contact temperature, disconnector position, insulator leakage and mechanical operations in real-time, you can optimize asset life-cycle efficiency, prevent failures, and ensure maximum substation reliability. 

  • Space-Saving Footprint: Our double-scissor design utilizes vertical separation, allowing substation designers to reduce space requirements by as much as 30%. A smaller substation footprint inherently leads to lower material usage for site civil works and construction. 

Engineered for the Most Challenging Environments

Backed by over 40 years of engineering excellence, GE Vernova’s SX disconnector is a rugged performer built for reliability in extreme conditions—from arctic cold and desert heat to high-seismic zones. 

  • Proven Durability: Stable in the closed position during short circuits and resilient against high winds and heavy ice. 

  • Operational Excellence: Streamlined contours reduce RIV and corona effects, while the counter-balanced blade design ensures low friction and simplified operation. 

  • Installation Flexibility: Whether installed directly below an overhead bus or at a diagonal crossover point, the SX provides the design flexibility required for modern substation layouts. 

Technical Data Summary (IEC)
  • Voltage Range: 72.5 kV to 550 kV 

  • Rated Current: Up to 5000 A 

  • Short Time Current: Up to 80 kA 

  • Standard Compliance: Designed, manufactured, and tested to the latest IEC/IEEE/ANSI and GB standards.
