Optical Ground Wire Cable for Power Transmission
Optical Ground Wire (OPGW) cable is designed for power transmission, integrating grounding and communication functionalities. It features optical fibers for data transmission, surrounded by layers of steel and aluminum wires for conductivity and mechanical strength.
Technical Specifications
Product Overview
Dual-Function Power Transmission Solution
Optical Ground Wire (OPGW) is an advanced composite cable designed for installation on both new and existing power transmission lines. It serves the dual purpose of acting as a traditional overhead ground wire for lightning protection and short-circuit current conduction, while simultaneously providing a high-capacity communication path via integrated optical fibers. This solution is ideal for normal and extra-high voltage power lines, enabling seamless grid monitoring and control.
