説明

Diameter 600mm Aviation Alerting Ball Overhead Cable and Guyed Wire Warning Sphere

Aircraft warning spheres are also called marker balls or aerial warning spheres are used as a visual marking of overhead power lines crossing fjords, valleys, and rivers, or generally everywhere there is a need to make power lines visible to aircraft and helicopters. The warning spheres are attached to the shield wires or to phase conductors, always to the wire or conductor having the highest point.

Aircraft warning 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. The power line marker ball is made of high-grade polyethylene, With a light-weight and integral design, the marker ball is easier to install on the power line

応用

Designed to use for high-rise transmission lines, especially for EHV (500,000KV) transmission cables, river-crossing transmission lines to provide the warning marks

Installation
1.At the mount point on the alerting ball, wrap cable protecting bars round cables for 1000-1200mm long, with two ends of
protecting bars extending 200-300mm beyond the surface of the ball.
2.Fix the plastic wires which are mounted on lower hemisphere of the ball onto the cables and twist them.
3.Combine the lower hemisphere with the upper hemisphere according to module codes. Turn the hemisphere during the assembly and make sure two hemispheres are joined into position .
4.Insert stainless steel bolt and then put flat washers and spring washers around each bolt. Tighten each nut at last.
