Night Marking Red Obstruction Light System for Transmission Tower

-
图片
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...

Aviation obstruction marking sphere is designed to provide daytime visual warning or nighttime visual warning if comes with reflective tape, for electricity transmission line and overhead wire for aircraft pilots, especially cross river high voltage transmission lines. CDT power line marker ball is made of high-grade Fiberglass Reinforced Plastics(FRP), diameter of 600mm and 800mm are available to meet different customers’ needs.  A marking sphere should be of one color such as aviation orange, white and red. Generally, the marking spheres are placed on the highest line. Where there is more than one line at the highest level, white and red, or white and orange spheres should be displayed alternately. This alternating color scheme provides the most conspicuity against all back ground. PARAMETER Name Aerial Marking Sphere   Model CM-ZAQ Operation Visible Distance 1200 meters Flashing frequency 35KV-1000KV Conductor diameter...

What Are Those Balls That Hang on Power Lines?

  When you are flying, the conductors and skyline become almost invisible against the terrain—especially the skyline  wires . The colored plastic balls hanging on overhead electricity wires are called aerial marker balls, and they are installed along the length of wires to act as a visual warning so low-flying aircraft don’t run into them. They're called visibility marker balls or marker balls.  You'll often find them near mountain passes, in the deep valley areas, near major freeway crossings and around airports. They weight about 17 pounds each. The marker balls are placed on power lines to make the conductor crossings visible to aircraft. Overhead wire markers are safety instruments applied to the overhead power lines marking transmission lines and ropeways along the flight path during the day. Markers are often installed on overhead lines near airfields, or at river crossings where there is a possibility of float-equipped...
