The full form of OPGW is Optical Ground Wire.

This name precisely describes the cable's dual function. It is a composite cable used on overhead power lines that combines a traditional ground wire with a fiber optic communication cable. The metallic component acts as a protective shield against lightning strikes, while the internal optical fibers provide a high-speed telecommunications link.

The integrated design of OPGW makes it a critical tool for modernizing and securing power transmission systems, which is why our company, Ningbo Changshi, specializes in the OHTL wire cable conductor tension stringing equipment and overhead tools and accessories required for its safe and efficient installation.
