Beaconing for line

ABS resin sphere

Designed and dimensioned for aerial beaconing on overhead ground wires and / or energy cables of 132 kV maximum, are available in two diameters (500 and 610 mm) and in three colours (Red, Orange and white).

The ABS resin coloured in the mass used for these spheres enhances their UV resistance and makes them highly durable.

Balisor high-voltage line beacons

The use of beacons on HV lines in areas concerned by air navigation regulations enable facilities to comply with such regulations.

These beacons specially designed for high voltage lines of 33 to 800 kV produce a red light with intensity greater than 10 Candelas.

These lamps are installed directly on the phase conductor with an antenna mounted in parallel to the power conductor creating an induced current adequate for energizing the lamp.

Wind socks

Used to indicate the strength and direction of the wind, both day and night, wind socks are installed on aerodromes, helicopter landing pads, road sides, leisure areas, sport grounds.

A wind sock is composed of :

- A tilting of 7,40m high white and red mast

- A wind vane 500 or 1000 mm in diameter

- A red and white wind sock diameter 500 to 1000 mm

Location of obstruction beacons

If an object is beaconed by low-or medium intensity obstruction lights and if the summit of the object is more than 45 m above the surrounding ground, or the height of the tops of surrounding buildings (if the object to be beaconed is surrounded by buildings) additional lights shall be installed at intermediate levels.

These intermediate lights shall be spaced as evenly as possible between the light placed at the summit of the object and the ground level or the level of the top of the surrounding buildings, as the case may be, and this spacing must not exceed 45 m.

The number and layout of the low, medium and high intensity obstruction lights to be installed at each of the beaconed levels shall be such that the object is beaconed from all directions…

Examples of beaconing

Light beacons on a crane

One light at the summit of the pillar, plus one level of lights for every 45 meter section. One light at the end of the beam, one light at the end of the counter beam. An intermediate light if the beam exceeds 50m.

Light beacons on a chimney (E.g. h=60m excluding service equipment)

Two levels of lights, each comprising three lights at 120° to each other.

Summit light : 1,5m to 3m above the summit.

Second level at the +30 m height (« equidistant»lights)

Beacons on a self-supporting tower (E.g.h=60m excluding service equipment)

At the summit : 2 twin lights overhanging in such a way that each light is visible from all directions, or, where this is not possible, 3 lights at 120° to each other around the periphery.

At the +30 m height approx. 3 lights at 120 ° to each other.
