Center Break Disconnector Switch type S2DA

  

The S2DA is reliable in high winds and heavy ice and always stable in the closed position during short circuits. A galvanised structural steel channel base supports the insulators and live parts, assuring a high strength, rigid design. The two insulator stacks rotate on weather-sealed, greaseless, maintenance-free rotor bearings and the blades are made of extra-heavy extruded aluminium with replaceable silver-plated copper contacts in the opening point.

• High short circuit carrying capacity
• No sliding contacts
• Low operating torque
• Built-in or retro-fitted earthing switches
• Arc restrictors for line charging and transformer magnetizing currents
• Virtually maintenance free
• Easy start-up and commissioning
