Conductor marking lights for overhead power lines

-
Why do we need conductor marking light for power line?

  • Conductor marking lights are a particular type of aircraft warning lights designed for overhead power lines. They are visible at night, unlike overhead wire markers which rely on daylight.
  • Conductor marking lights increase night conspicuity of transmission line catenary wires near airports, heliports, across rivers. Lamps mark and light overhead power lines support structures (towers) as well as high voltage transmission line catenary wires.It is one assembly light with multi-LEDS technology. Dedicated to the beaconing of high voltage lines,it is a long life system (100,000 hours). Its compact design and light weight allow the quickest and easiest installation on the market.
How does this condcutor marking light worked?


The conductor marking light is based on Faraday's Law of induction involving Magnetic Flux flowing through a circuit which powers the warning light.
The Warning light is powered by the magnetic field surrounding the power distribution wire and uses an electronic circuit integrated in a compact clamp-on warning light. The operating principle is that of a Rogowski coil, similar to a current transformer. This solution is usually intended for medium and high voltage lines up to 500 kV. However inductive coupling devices are able to work on any AC at 50 Hz or 60 Hz, from 15A up to 2000A.

Where does this conductor marking light used?
  • Transmission Line
  • Overhead Power Line
  • Low,medium and high voltage lines

Night Marking Red Obstruction Light System for Transmission Tower

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. Red obstruction lights are used to increase conspicuity during nighttime. The red obstruction light system is composed of flashing omnidirectional lights (L-864) and/or steady-burning or flashing (L-810) lights. When one or more levels are comprised of flashing lights, the lights should flash simultaneously 1. Single Obstruction Light. A single red obstruction light (L-810) may be used when more than one obstruction light is required either vertically or horizontally, or when maintenance is needed, and can be installed within a reasonable time. Top Level. A single steady-burning light (L-810) may be used to identify low structures, such as airport instrument landing system buildings, as well as long horizontal structures, such as perimeter fenc...

ICAO compliant MIOL red flashing solar obstruction lights are an integrated solution including a high-efficiency LED light source, solar panels and battery. In remote areas, where 110V or 220V is not available except at extremely high cost, solar-powered FAA & ICAO obstruction lights have become the preferred and often necessary solution for marking utility transmission towers, telecom towers, wind farm testing, airports, and other tall structures. Tapping into solar energy is simpler and greener, saves money, and keeps lights off the grid. The system is designed as a compact, all-in-one solar system, completely self contained for easy installation. The high efficiency, compact design provides end users with a lightweight, maintenance free power solution, requiring minimal surface area for installation. The system is ideal for remote airstrips where hard-wired infrastructure is unavailable.

Overhead Wire Marker Fiberglass Aircraft Warning Sphere Day Marking  Aerial Marker Balls for High Voltage Power Lines  Warning sphere is used for warning aircraft pilots in daytime and nighttime, which is compliant with International Civil Aviation Organization (ICAO) recommendations annex 14 chapter 6. It can be used in overhead cable, guyed wire, especially in extra high voltage power transmission line, cross river power transmission line, cross road, bridge power transmission line and so on. It is made of high-grade polyethylene with the color of red, orange, white. Different colors' warning sphere should be displayed alternately. If there are many lines, warning sphere should be displayed on the highest line. It can resistant to corrosion, rust, water, dust, high temperature, can be used for long time.
