AVFD-HCR (B10) Avian Flight Diverter

High Contrast, Drone Installable, Multi-Dynamic, Avian Flight Diverter

TE Connectivity (TE) Avian Flight Diverters High Contrast Reflective AVFD-HCR are designed to increase visibility of overhead lines, helping birds detect and avoid potential collisions. By making lines more noticeable, large birds such as geese and swans have additional time to change direction, reducing the risk of injury and infrastructure damage.

The AVFD-HCR features high-visibility, contrasting reflective elements that enhance daytime visibility. Multiple independent tabs with intermittent high-contrast colors further improve detection, supporting effective bird-strike mitigation.

Compatible with a wide range of conductor types, with RFI testing conducted up to 173 kV, and suitable for use on ground wires regardless of system voltage classification. The diverters fit conductors up to 50 mm in diameter and are secured using high torsional strength springs that provide clamping forces greater than 100 N (22.48 lbf), ensuring stability in diverse weather conditions.

Installation can be performed using a hot stick, by drone, or by an aerial remotely operated vehicle, enabling efficient deployment on energized or hard-to-access lines. The diverters are also removable, simplifying inspection and maintenance.
