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
Main Characteristics

Drawings
  • 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
