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
