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 15-60

Building Light-Building Obstruction Light/Rooftop Heliport Lighting

Buildings lighting Obstruction lighting solutions to be set at the top of buildings, and heliport lights, to be set around the runway in order to guide helicopters pilots. Lighting of buildings with heliports If the building has an elevated heliport, that is to say located on a raised structure on land, lighting marks have to be set around the runways to guide the pilots during take-off and landing. In the case of these elevated heliports, the Final Approach and Take-Off areas (FATO), and the Touchdown and Lift-Off areas (TLOF) are coincidental: only the TLOF runway matters. As a matter of facts, TLOF area should be lighted with TLOF perimeter lights: fixed omnidirectional green lights, inside the floor, or not higher than 25cm, uniformly spaced from 3 meters maximum. It will be possible to add floodlights to the perimeter lights, in order to identify better the heliport marks.  Lighting of buildings judged as air obstacles In t

L-806 L-807 LED Lighted Wind Cone with Obstruction Light/Illuminated Wind Sock

A windcone is a carefully designed fabric cone that is mounted on a metal frame. This metal frame is attached to a vertical pole via a swivel that allows the fabric cone to rotate freely. The fabric cone must be designed to provide relative wind speed indication. A fully extended windsock indicates a wind speed in excess of 15 knots. An illuminated windcone must be powered in some manner. Common methods are with 120VAC/240VAC or 6.6Amp circuitry. Recent advances in both LED and solar power technology have allowed for the creation of reliable and compliant solar powered LED windsocks. Wind Direction Indicators or wind cones provide visual surface wind direction and velocity information to pilots in flight or on the ground at airport and heliports. We based our wind cone portfolio on FAA specifications OPTIONS  1. Fabric Windsock: Size 1- 1.2m length, 300mm in throat diameter and 150mm in trailing end diameter; Size 2- 2.4m length, 600mm in throat diameter and 300mm in trailing end diame
