Power Line Optical Cable Ground Wire Connection Method
This article presents installation methods for replacement of the conventional ground wires with Optical Ground Wires (OPGW) under live power transmission lines. It is composed of AS wire, AA wire and stainless steel tube optical unit. An OPGW cable contains a tubular structure with. In principle, the tension pay-off method is adopted. Suitable tension should be maintained to keep OPGW hanging in the air to avoid abrasion of the OPGW cable on the ground. Optical Ground Wire (OPGW) integrates optical fibers into an overhead ground wire, combining the functions of a power line ground wire and a telecommunication cable. It ensures. Recommendation ITU-T L.
