In general, the maximum stringing tension should be a half of the maximum sagging tension and never should exceed 20% RBS of the OPGW. “Radius Blocks,” “Banana Blocks” or “Array Travelers” as shown below in Figures 2A-C are strictly prohibited during the installation of OPGW. NOTE: Based on actual OPGW size, etc., care must be. OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system, adding of communication lines and conduction of short-circuit current. worldwide quality standards. Prysmian has a built-in multi-step quality assurance programme, which covers the entire production process from cable design and raw materials purchasing, to final inspecti tion for any single project. Installed at the top of high-voltage and extra-high-voltage transmission lines, OPGW cables provide lightning. This specification covers COMCAST® OPGW for the installation on high voltage overhead power lines. They adhere to international 1 and local standards 2 to ensure safety, functionality, and durability, making them essential for modern.
