OBSTRUCTION LIGHTING FOR HIGH VOLTAGE POWERLINES
High-voltage lines are major hazards for low-flying 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. The power supply by capacitive effect ensures a constant light intensity whatever is the value of the electric current crossing the line, even without current, the balisor lamp remains visible with light output above ICAO minimum requirements
Balisor conductor warning light (catenay lighting) for high voltage cable for night marking are available from 500KV to 90KV
The obsta spherical markers are compliant with International Civil Aviation Organisation (ICAO) annex 14 chapter 6 recommendations: Paragraph 220.127.116.11: A marker displayed on an overhead wire, cable, etc., should be spherical and have a diameter of not less than 60 cm Paragraph 18.104.22.168: The spacing between two consecutive markers or between a marker and a supporting tower should be approriate to the diameter of the marker, but in no case should the spacing exceed 30 meters when the marker diameter is 60 cm. Where multiple wires, cables, etc., are involved, a marker should be located not lower than the level of the highest wire at the point marked
Our warning spheres made in polyethylene are available in orange aviation, red aviation or white UV and Ozone resistant. The jaws are large and made in EPDM suitable for armor rod and conductor cable.
Our warning spheres made in aluminium have been designed for high temperature conductor

Obstruction lights for catenary structures
The marking of high voltage transmission lines must be ensure by DC obstruction lights with solar power stations, the size of the battery and solar panel depends on latitude and longitude. Based on NASA sunshine database, we design and size our solar kits optimally and with gel batteries best suited to local temperatures.
