The innovative design of OPGW makes it an indispensable component for today’s power grid. Its two main functions are:

1. Overhead Ground Wire (Static Wire) Protection: The outer metallic layer of the OPGW cable is highly conductive. Its main purpose is to be the first point of contact for lightning strikes, safely directing the high electrical current to the ground. This shields the sensitive power conductors below from damage, which is crucial for preventing blackouts and maintaining the stability and reliability of the electrical grid.

2. Fiber Optic Communication: Encased within the protective metallic layer are optical fibers. These fibers are the communication backbone for the power utility, enabling the transmission of large amounts of data at high speeds. This function supports a wide range of applications, including:

   • SCADA (Supervisory Control and Data Acquisition) systems for real-time monitoring and remote control.

   • Fault detection and locating.

   • Telecommunications for utility operations.

   • Grid automation and smart grid technologies.

By integrating both of these functions into one cable, OPGW offers a cost-effective and secure solution that eliminates the need for a separate communication cable. At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we manufacture the specialized overhead tools and accessories and tension stringing equipment required for the safe and efficient installation of these multi-functional OPGW cables.
