OPGW, or Optical Ground Wire, is a dual-purpose cable used in overhead power transmission lines to provide both grounding and high-speed data communication. It combines the functions of an overhead ground wire, which protects power lines from lightning, with optical fibers that transmit data over long distances. The cable consists of a protective outer layer of steel and aluminum alloy wires, with optical fibers housed in a central tube. OPGW cables are designed to withstand harsh environmental conditions. Common types are based on the central tube material, which is often aluminum-clad steel or stainless steel. Some designs use a central tube, while others strand multiple tubes along with wires. Dual functionality: Reduces the need for separate ground wires and communication lines, leading to cost savings and simpler installation. High reliability: Built to withstand harsh weather, high
