Lightning Resistant OPGW

Suitable for transmission lines in areas with frequent and strong thunderstorms.

(1)Circular or irregular aluminum clad wires can be designed according to engineering requirements; (2)Meet the requirement of no wire broken at 200C; (3)Solve the technical problem of OPGW being damaged by lightning strikes in areas with frequent thunderstorms, and passed the appraisal in 2008.

IEC 60794-4-10	Aerial optical cables along electrical power lines – Family specification for OPGW
IEEE1138-2009	IEEE Standard for testing and performance for optical ground wire (OPGW) for use on electric utility power lines

1.Adopt all aluminum clad steel wire structure;

2.Increase the diameter of the outer wires,the diameter is≥3.0mm,and some areas with high thunderstorm days are≥ 3.2mm;

3.Design a larger OPGW diameter,and design inside small outside large 1+6+10 non-equal diameter stranded;

4.The OPGW with compressed wires is adopted,and the aluminum-clad steel wire is pressed into a fan shape through a special process,so that each layer is twisted more compactly,the diameter of the inner layer is reduced,and the diameter of the outer layer wire is increased,and the lightning resistance performance of the OPGW is improved.
