PVC Bird Diverter for overhead conductors

PVC Bird Diverter is designed for use on overhead conductors to create greater visibility for avian flight paths on overhead lines and tower down guys. Offering little wind resistance, it reduces hazards to both lines and birds. For low and medium voltage construction, apply flight diverter to phase conductors (bare or jacketed). For high voltages, it is typically used on shield wire.
Flight diverter is lightweight, offers little wind resistance and is easily and quickly applied by hand or hot stick. The positive grip on the conductor is designed to ensure that flight diverter remains in the applied location and does not move along the span under Aeolian vibration or other conditions.

PVC Bird Diverter

1.Materials:
Manufactured from rigid high impact polyvinyl chloride (PVC), Fly diverter possesses excellent chemical resistance, strength properties and will retain good physical characteristics within a range of extreme temperatures. Industrial fumes and salt water cannot seriously degrade the properties of rigid PVC.

2.Spacing
For optimal results, spacing distances are generally recommended at 15' intervals,depending upon local conditions. Since wind resistance is very limited, sufficient SWAN-FLIGHT Diverters can be used to ensure adequate visibility without creating stresses on the line. When marking adjacent spans, overall visibility is improved by staggering the placement between the spans.
