Cable Spacers / Spacer Dampers by PFISTERER Ges.m.b.H.
Best Solution for Each Bundle Configuration
For high voltage transmission lines, conductor bundles are used for each phase to fulfil electrical requirements.
Spacing devices are installed on the bundles to maintain subconductor separation. Elastic and damping elements are introduced into the spacing devices for distributing the damping effect along the spans which prevents
entrapment of vibration between Spacer Dampers and avoids bending stresses at the clamps.
PFISTERER has been developing Spacer Dampers since 1980 to provide the correct damping of wind-induced vibrations for bundled conductor lines.
Modern Spacer Dampers are characterized by an accurate coordination between the inertial and elastic damping properties. This provides maximum effectiveness in controlling the levels of subconductor motions.
