OPGW Center Tube Optical Fiber Composite Overhead Ground Wire<\/p>\n\n\n\n

The OPGW (Optical Fiber Composite Overhead Ground Wire)<\/strong> is a multi-functional aerial ground wire designed for high-voltage transmission systems. It serves the dual purpose of a traditional ground wire\u2014providing lightning protection and conducting short-circuit currents\u2014while simultaneously acting as a high-speed optical communication medium. It is primarily utilized in 110KV, 220KV, 500KV, and 750KV power systems.<\/p>\n\n\n\n

\n\n\n\n

Core Product Characteristics<\/strong><\/h3>\n\n\n\n
    \n
  • Superior Protection:<\/strong> High-tensile stainless steel tubes protect the optical fibers from external mechanical stress.<\/li>\n\n\n\n
  • Enhanced Reliability:<\/strong> Provides effective grounding and lightning protection for high-voltage transmission lines.<\/li>\n\n\n\n
  • Optimized Design:<\/strong> Features a small diameter and lightweight construction to minimize additional mechanical load on utility towers.<\/li>\n\n\n\n
  • Fiber Integrity:<\/strong> Maintains a suitable primary excess length of optical fiber within the optical unit to prevent signal loss under tension.<\/li>\n<\/ul>\n\n\n\n
