OPGW optical cable (Optical Fiber Composite Overhead Ground Wire) is a revolutionary product in the field of power system communication. It perfectly integrates traditional overhead ground wire with optical fiber communication technology. It is not only a lightning protection device for power lines, but also a high-speed data transmission channel.
Core structure analysis:
·Outer structure: aluminum-clad steel or aluminum alloy stranded wire, providing mechanical strength and lightning protection.·Fiber unit: Contains 4-144 core G.652/G.655 single-mode optical fiber.
·Buffer layer: stainless steel tube + water-blocking material, double protection design.
·Temperature tolerance: stable operation in extreme environments from -40℃ to +80℃.
