The High-Temperature Air Flow Spoiler is constructed of aluminum alloy rods that enable the device to withstand conductor temperatures up to 250ºC. By subsetting multiple helical rods and cabling (twisting) the center section, the High-Temperature Air Flow Spoiler functions in the same manner as the standard Air Flow Spoiler.

  • 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 extensive field and laboratory research

  • Contact PLP for details regarding High-Temperature Air Flow Spoiler applications above 230 kV
