<p>PROBLEM TO BE SOLVED: To provide a clamp for grasping an optic overhead ground wire(OPGW) without the generation of corrosion of the OPGW, loss increase in optical fiber and wire breakages, in the clamp for holding OPGW. SOLUTION: In an internal peripheral surface of clamp for grasping OPGW 1, a plurality of water drainage grooves 7 having rectangular cross section are provided radially with a clamped OPGW serving as the center. Through the water drainage groove 7, phenomenon of capillarity is prevented, flow of water in the OPGW holding clamp 1 is improved, insulator wash water, rainwater, etc., including salt corroding the OPGW are prevented from accumulating in the clamp.</p> |
