Obstruction Light Kit for Power Transmission Tower

Model No. : ATV-TL-04
(Suitable for 50 meter High Power Transmission Tower


The whole system can be used for 50 Mtr Transmission Line Towers Powered by solar energy. Medium Intensity AWL could be placed at top of the tower. Avaids make Medium Intensity Type ‘B’ Aviation Warning Light as per ICAO annexure - 14 and FAA type L – 865 specifications. Operates in night mode only & provides Multi directional ‘Red’ flashing light with intensity of 2000Cd. Beam Divergence: Horizontal 360˚ with Vertical 3˚

  • Features
  • The system consists of 1 Medium Intensity to be installed at the top of the tower. Similarly, solar module and battery has to be installed as nearer to the light as possible
  • A photovoltaic module is installed with the system which not only charges the battery but also senses ambient natural light intensity and allows the system to turn ON the AOL, when the natural light intensity falls below a certain predefined threshold level during dusk to dawn or due to local climatic conditions.
  • LVD: - Low voltage disconnect of load (at which charger will disconnect load) – 10.5V
  • LVD : reconnect voltage (at which voltage load will reconnect) – 12.8 V
  • HVD: - High voltage disconnect (at which Solar charger will disconnect charging) – 15.2V
  • VRLA batteries have to be charged only in constant potential, current limiting mode. Charging current to be limited to 10-20% of Ah capacity of battery. Recharging to be done immediately after discharging, less or late charging of batteries may less the life of battery.
  • Dusk to Dawn operation would be done by Photovoltaic module.
