What are the main applications for OPGW cables?

2025-08-10

OPGW cables are primarily used by the electric utility industry on high-voltage overhead transmission lines. Their applications include:

  1. Telecommunications: They provide a high-speed path for voice, video, and data transmission for the utility's internal use and can also be leased to third-party telecommunication companies, generating additional revenue.

  2. Smart Grid Integration: OPGW serves as the communication backbone for smart grid technologies, facilitating data exchange for better monitoring, control, and efficiency.

  3. SCADA Networks: It is essential for Supervisory Control and Data Acquisition (SCADA) systems, which are used to remotely monitor and control equipment at substations.

  4. Retrofit Projects: OPGW is a popular choice for replacing existing traditional ground wires on older transmission lines to modernize the infrastructure.
