Optical ground wire

AFL is adding to its Optical Ground Wire product line by introducing Renewables’ Optimized Optical Ground Wire (OPGW), an aerial fiber-optic cable that’s specifically designed for the renewable energy markets, including for wind and solar projects. OPGW allows for greater ease and flexibility in installation timelines, while providing excellent electrical and mechanical properties. AFL’s OPGW is to be placed at the topmost position on transmission lines to shield conductors from lightning and, at the same time, provide a fiber-optic communication pathway. 
  
Taking advantage of AFL’s CentraCore OPGW features, the cable’s compact and robust design houses 48, single-mode optical fibers in gel-filled, laser-welded, hermetically sealed stainless steel tubes. These tubes help protect the vulnerable fibers from environmental stresses and electrical faults. Additionally, thick outer layers of aluminum-clad steel wire and aluminum pipe provide excellent crush-resistance, enhancing the fault-current rating capability.
