How do you choose a vibration damper for an overhead line?
Aeolian vibration from steady laminar wind fatigues conductor strands at support points, and dampers are the standard countermeasure. The common families are the weight-and-cable (Stockbridge) type for longer spans and larger cross-sections, and lighter spiral dampers for smaller distribution conductors. Selection is driven by span length, conductor size and type, terrain and wind exposure — Silverstone Electric supplies dampers matched to your line design from Suzhou, China.

Frequently asked
When does a line need dampers?
Long spans, open flat or coastal terrain and larger smooth conductors are the classic triggers, and many utilities specify dampers by rule above certain span lengths. Share your span schedule and a placement recommendation comes back with the quotation.
Stockbridge or spiral type?
Longer transmission spans and heavier conductors typically take weight-and-cable dampers; short distribution spans and smaller conductors often take spiral types. The final call is made on the span and conductor data.
Can placement be specified for us?
Yes — send conductor type, span lengths and terrain notes; damper quantities and positions are returned with the quotation.
