24 Core OPGW Cable is designed for overhead transmission networks where reliable grounding protection and high-speed optical communication are required. Combining the functions of an optical fiber cable and an overhead ground wire, it provides a practical solution for modern power grid communication systems.
Manufactured by Zhongdong Cable, this OPGW cable features high-quality G.652.D single-mode optical fibers with excellent transmission performance and low signal attenuation. The aluminum-clad steel wires and aluminum alloy components provide strong mechanical strength, corrosion resistance, and long-term stability under outdoor conditions.
With a compact structure, high tensile capacity, and compliance with IEC 60794 and IEEE 1138 standards, the cable is suitable for high-voltage and extra-high-voltage overhead power lines. It helps power utilities improve grid monitoring, protection communication, and operational efficiency while reducing the need for additional communication infrastructure.
