Our high-quality laser welding system includes proprietary orbital seam tracking, ensuring precise results. This system adapts laser power and beam quality to suit specific applications, including long-length cables such as submarine cables. THE Machines Yvonand SA designs, develops and engineers 'in-house' all optical fibre handling, metal forming and laser welding lines. Components are engineered and manufactured to the highest standards, technologies and precision, resulting in unsurpassed productivity, line performance and. 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. Application 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. An optical fiber composite overhead ground wire (OPGW) is a new type of ground cable used in the high-voltage power transmission system that serves as both a conventional overhead ground cable and a communication optical cable. The specification describes the basic design of COMCAST® OPGW with its main.
