SPV
Semi-Pantograph Disconnector up to 1,000 kV

The SPV 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%.


Customer Benefits
  • Reduced substation space requirements (up to 30%)
  • Clear conducting routing for safety
  • Rigid or flex busbars for flexibility
  • Built-in or retro-fitted earthing switches
  • Virtually maintenance free
  • Easy start-up and commissioning
Main Characteristics
Specifications
Drawings
  • Blades are extra heavy, one piece, tubular aluminium with replaceable silver plated copper contacts at each end
  • Galvanized structural steel channel base supports the insulators and live parts, providing high strength and rigid design
  • All bearings and counter-balancing springs are isolated from the main path
  • Clear busbar arrangement and routing results in increased safety during operation and maintenance
  • In open position, blade sections fold upon themselves, offering maximum dimension slightly greater than half the open gap dimension.
  • More compact than a standard pantograph switch and streamlined contours reduce RIV and corona effects
  • Flexible installation and arrangement configurations
  • Virtually maintenance free with factory-sealed bearings, life-time greased or self-lubricating parts and corrosion-free materials
