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
