Beschreibung
Zusammenfassung:	A seismic isolation device is described, which is adapted for application to the base of a switch for a high-voltage electric system, characterized in that it comprises: - a first metallic plate (1), square in shape, adapted to be fixed to a basement; - a second metallic plate (2), adapted to be fixed to the switch base; - four dampers/isolators of the wire-rope type (3), connected between said first and second plates, mutually arranged at the vertices of a square, and oriented at a 45° angle relative to the sides of said first plate.
