Specifications

Installation

• Mounted on the wirerope of lightning protection ground of the overhead tower. The distance between each two spheres is the following:

a, if the diameter of sphere is 600mm, the distance is no more than 30m

b, if the diameter of sphere is 800mm, the distance is no more than 35m

c, if the diameter of sphere is 1300mm, the distance is no more than 40m, Equal Interval setting 。

• It has red, white, orange. The setting should be interphase.

• Involved multiterm lines, cables situation, the height of the spheres should not be lower than the height of the highest marked overhead line. 

Note:

• Line diameter can not exceed the range regulated by the clamp, designated for the special situation.

•  Choose two different colors spheres at the meanwhile, interphase setting.
