The acronym OPGW stands for Optical Ground Wire.

It is a specialized type of cable used in overhead power line construction. The term is descriptive of its dual-purpose nature: it functions as both an electrical ground wire and a high-speed optical communication cable. The metallic outer strands provide the necessary grounding and protection against lightning, while the internal optical fibers enable telecommunications.

This innovative combination allows power utilities to protect their grid while simultaneously building a reliable and secure communication network. At Ningbo Changshi, we provide the one-stop solution for the tension stringing equipment and overhead tools and accessories needed to install and maintain these advanced OPGW cables with precision and safety.
