Use a grounding wire: Use a dedicated grounding wire to connect the metal reinforcement core or armor layer in the optical cable to the grounding electrode or the building's grounding system. Such cable combines the functions of grounding and telecommunications. An OPGW cable contains a tubular structure with. OPGW is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it “shields” the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. It deals with the factors that should be considered in determining the characteristics of this type of cable, the apparatus that should be used, the precautions that should be taken in handling the reels, and. Optical cable grounding is an important measure to protect optical cables and their connected equipment from lightning strikes, electrostatic discharge and electromagnetic interference.

Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. This helps to reduce the potential difference that exists between conductive parts and the earth. It also describes the methods for improving soil resistivity. These locations are usually marked with grounding symbols for easy cable crimping. Flexible Connection: Braided copper tape.
An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and telecommunications. Application OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system. Optical Ground Wire (OPGW) is a composite cable that integrates optical fibers within a metallic ground wire.
