Application of warning sphere
Our polyethylene warning spheres are used in overhead cable, guyed wire, supporting tower, especially in super high voltage power transmission line, cross river power transmission line, cross road, bridge power transmission line and so on.
Installation: Five steps for warning sphere installation.
Warning sphere installation note
- The spacing between two consecutive warning spheres or between a warning sphere and a supporting tower should be appropriate to the diameter of the warning sphere. The maximum spacing is 30 m with sphere's diameter is 600 mm.
- If multiple wires or cables are involved, warning sphere should be located in the highest wire.
- When installed, different colors' warning spheres should be displayed alternately. The color selected should contrast with the background to ensure marker balls will be seen clearly.
- Warning spheres should alternate aviation orange, white, yellow, with aviation orange markers positioned at each end.
- If less than four markers are on the line, all markers should be aviation orange.
