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). Night marking The BALISOR® cold neon discharge type created by OBSTA in the 60's is a beacon for high voltage lines working by capacitive effect. The power supply by capacitive effect ensures a constant red fixed light intensity above 10 candelas matching with ICAO aviation. This light intensity remains constant whatever is the value of the electric current crossing the line, even without current the balisor lamp remains visible with light output matching with ICAO minimum requirements. The number of capacitive elements depends on the voltage of the lines : Our standard balisor cold neon discharge type exist in 3 main configurations for 380KV or higher, 220KV and 132KV AC network The inductive balisor (HVLite series) requires at least 15A to reach the minimum red fixed light intensity defined by ICAO recommendation DescriptionModel 1 Cold neon discharge neon typeB380 1 Balisor 360KV and moreB380 1 Balisor 210KV to 360KVB220 1 Balisor 130 to 160KVB132 2 LED typeB380 2 Balisor HVLiteHVLite Day marking Our spherical markers are compliant with International Civil Aviation Organisation (ICAO) annex 14 chapter 6 recommendations: Paragraph 6.2.5.4: A marker displayed on an overhead wire, cable, etc., should be spherical and have a diameter of not less than 60 cm Paragraph 6.2.5.5: 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 up to 70°C . Our warning spheres made in aluminium have been designed for high temperature conductor and tested up to 250°C peak DescriptionModel 1 Sphere for OPGW, ground cable, guy-wire cable 1 Sphere for OPGW and ground cableSPHERE600 1 Low intensity for OPGW and ground cableNAVILITE-CLAMP 1 Sphere for high temperature cable 2 Aluminium warning sphereSPHERE600-AL 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 12Vdc or 48Vdc solar kits optimally and with gel batteries best suited to local temperatures. If markers are installed on the cables, the towers supporting the cables should follow the same requirement for towers as per ICAO annex 14 chapter 6 (see this link obstruction-lights-on-tower) If it is not possible to install markers on the cables, 3 levels of high intensity type B (or medium intensity in some case) shall be installed, consult us for more information Example of installation Day and night obstruction light systems with complete solar kit in Europe Night only operation system low intensity type Infrared and red solar power obstruction lights in Sweden And for the remote control of your DC obstruction lights and DC solar kit, OBSTALINK IoT gateway is the solution to control your complete obstruction lighting systems including the complete solar power unit DescriptionIOT gateway OBSTALINK 1 OBSTALINK DCOBSTALINK
