SPVL
Semi-Pantograph Disconnector up to 1,000 kV
The SPVL is a space saving vertical reach disconnector connecting the lower busbar to the upper one via the semi-pantograph arm. Horizontal rather than vertical separation means a space reduction of as much as 30%. The SPVL is equipped with unique pollution and ice-free L-Contact.
Customer Benefits
- Reduced substation space requirements (up to 30%)
- Pollution and ice-free L-contact
- Tested for up to 10,000 operations
- Built-in arcing horns and bus transfer contacts
- Built-in ground switches available
- Virtually maintenance free
- Easy start-up and commissioning

- Built-in arcing horns and bus transfer contacts
- Built-in ground switches available
- Virtually maintenance free
- Easy start-up and commissioning
- Flexible installation and arrangement configurations
- Unique L-contact design for switches used in heavily polluted or iced sites, and where extended mechanical endurance (10,000 operations) is required
- Blades are extra heavy, one piece, tubular aluminium with replaceable silver plated copper contacts at each end
- In open position, blade sections fold upon themselves, offering maximum dimension slightly greater than half the open gap dimension
- Clear busbar arrangement and routing results in increased safety during operation and maintenance
- Virtually maintenance free with factory-sealed bearings, life-time greased or self-lubricating parts and corrosion-free materials
