GE’s SPO is a vertical break disconnector with a two-piece arm. In the open position the blade sections fold upon themselves in a vertical plane of only 60% of the longitudinal dimension. The SPOL is equipped with the unique pollution and ice-free L-Contact and bus transfer contacts.

Customer Benefits
  • Pollution and ice-free L-contact
  • Reduced vertical space requirements
  • Built-in ground switches and arc restrictors available
  • Virtually maintenance free
  • Easy start-up and commissioning

GE’s SPO is a vertical break disconnector with a two-piece arm. In the open position the blade sections fold upon themselves in a vertical plane of only 60% of the longitudinal dimension. The SPOL is equipped with the unique pollution and ice-free L-Contact and bus transfer contacts.

Customer Benefits
  • Pollution and ice-free L-contact
  • Reduced vertical space requirements
  • Built-in ground switches and arc restrictors available
  • Virtually maintenance free
  • Easy start-up and commissioning

  • Unique L-contact design for switches used in heavily polluted or iced sites, and where extended mechanical endurance (10,000 operations) is required
  • Substation crossing structures and wires can be lower and less expensive than conventional vertical break disconnectors
  • Low center of gravity for live part provides high performance during earthquakes and faster, smoother and rebound-free operation
  • Virtually maintenance free with factory-sealed bearings, life-time greased or self-lubricating parts and corrosion-free materials
