Power line fiber optic cable are various composite cables and special optical cables that are used in power systems to give consideration to both power transmission and communication network. Typical fiber cable structures for power line fiber optic cable system are the OPGW and ADSS.
OPGW means optical fiber composite overhead ground wire. Optical fibers are placed in the ground wire of the overhead high-voltage transmission line to form an optical fiber communication network on the transmission line. Therefore, the OPGW optical cable has the dual functions of ground wire and communication.
ADSS is all dielectric self supporting fiber optic cable. It has no metal, tension resistance, self supporting, high insulation, non-inductive, small diameter and light weight. As a result, the ADSS cable is easy for construction and has economic efficiency.
