Damp — spacer dampers for bundled phases (including Nutcracker)
Damp spacer dampers with flexible damping joints keep the geometry of a bundled overhead line phase and suppress aeolian and subspan oscillation. Their placement along the span is determined by calculation.
- Purpose
- keeping the geometry of a bundled phase and suppressing aeolian and subspan oscillation
- Nutcracker clamp
- for hot conductors up to 210 °C, rubber-lined, with locking latch
- Standard
- IEC 61854
- Design
- individual damping calculations, field vibration measurements

Description
The Nutcracker clamp is designed for hot conductors up to 210 °C; it is rubber-lined and has a locking latch. The products comply with IEC 61854. Individual damping calculations are made for each line and, if needed, field vibration measurements are carried out. The results determine the number of spacers and the distances between them in the span.

Questions and answers
Which vibration do the spacer dampers suppress?
Aeolian and subspan oscillation of the bundled phase, while also keeping its geometry.
What conductor temperature is the Nutcracker clamp designed for?
For hot conductors up to 210 °C; the clamp is rubber-lined and has a locking latch.
How is the spacer placement determined?
By an individual damping calculation, with field vibration measurements if needed.
