The Air Flow Spoiler is a motion control product used to control galloping of cable spans. Galloping can rapidly cause severe damage to the cable systems if left unmitigated. Using the recommended quantity and placement of Air Flow Spoilers can suppress galloping and increase cable longevity.

  • Central spoiling section suppresses galloping by providing a constantly changing aerodynamic profile, disrupting lift

  • Helical gripping sections on both ends grip the cable securely without excess clamping forces

  • Number and placement of Air Flow Spoilers in each cable span are determined by an internally-developed program based on the results of field and laboratory research

  • Made of durable, UV-rated PVC

  • Standard version available for up to 230 kV and EHV available for up to 345 kV

  • Air Flow Spoilers for EHV applications have a co-extruded semi-conductive material layer that resists the surface effects of high electrical gradients and minimizes the possible generation of radio interference (RI).
