Obstruction lighting system for high voltage lines 360KV and more

High-voltage lines are major hazards for low-fl ying aircraft. Placing beacons on pylons is not sufficient to ensure safety due to the very long spans of cable (extract of Aerodrom Design Manual chapter 14.7 annex 4).

The BALISOR® system (created by OBSTA in the 60's) is a beacon for high voltage lines. Its conductors take the power required directly from the line.

The system is , therefore, completely self-contained.

Our standard model of BALISOR® fall into the ICAO low intensity category.

The neon discharge offers :

  • Inherent generation of «aviation» red light,
  • A very long life, essential to continuous operation of highvoltage lines.
  • Light intensity remains the same whatever is the current crossing the high voltage cable.
