Abstract Description: The deployment of Optical Ground Wire (OPGW) on 765kV transmission lines presents unique engineering challenges and opportunities for utilities seeking to enhance grid reliability and communications. This presentation explores OPGW design considerations, including fiber selection, mechanical strength, and electrical performance tailored for ultra-high voltage environments. Special attention is given to the integration of accessories such as isolators, suspension clamps, vibration dampers, and grounding hardware, which are critical for maintaining system integrity under extreme electrical and environmental conditions. Drawing on recent field installations and laboratory testing, the session will address best practices for mitigating corona discharge and ensuring compliance with evolving utility standards. Attendees will gain insights into supply chain management for OPGW components, strategies for minimizing lead times, and lessons learned from large-scale deployments. The presentation will also highlight future advancements in fiber technology and accessory design, supporting utilities in their transition to resilient, high-capacity networks. This session is ideal for utility engineers, transmission planners, and asset managers involved in the specification, installation, and maintenance of OPGW systems for 765kV applications.
