Answer:

• OPGW cables are primarily used in the electric utility industry for high-voltage transmission lines. They serve as a crucial component for lightning protection, grounding, and high-speed data transmission for SCADA (Supervisory Control and Data Acquisition) systems, voice, and video communication.

• ADSS cables are widely used in various telecommunication applications. Their self-supporting design and resistance to EMI make them suitable for installation on power distribution and transmission poles, railways, and other aerial environments where adding a new ground wire is not feasible. They are commonly used for FTTX networks, broadband, and long-distance communication.
