Aerial/Aircraft Warning Marker Spheres were installed in line with the International Civil Aviation Organization (ICAO) and National regulations. The warning spheres on the earthwire shall be international orange color, spaced 60 m(meters) apart, and the AWS shall be placed in an alternating fashion to maximize the visibility of the overhead earthwire under all weather conditions and hence minimize aircraft collisions with the transmission line. The installation of AWS will be done by using preformed armor rods compatible with the diameter of the OPGW conductor.

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...

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...

Aerodrome Beacon Light 4 LED Lamps 12 rpm, 24 flashes per minute White/Green Airport Rotating Beacons  CM-HT12-XZ-4 Rotating Beacons are designed primarily for night operation as identification and location markers for airports. Airport beacons help a pilot identify an airport at night. The beacon typically rotates at a constant speed, which produces the visual effect of coloured flashes at regular intervals. The combination of light colours from an airport beacon indicates the type of airport.  Key Feature Application Environment Above 2,500 meters above sea level; Outdoor: -40°C--+55°C; Relative air humidity: 95%; (+24.5 ° C), the maximum humidity can be greater than 100%; Between rain, snow, and ice; Corrosive salt spray. Technical Index 4 LED lights Lamp life: ≥50000 hours White, green, two-color lamp Lamp angle adjustable , 12 rpm, 24 flashes per minute ,Steel cabinet with powder layer , Voltage AC220V (DC optional) PARAMETER Item Name Airport Rotating Beacon Model CM-HT1...
