SPOL
Knee Type Disconnector up to 1,200 kV
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

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
