Its three most important basic parameters are the diameter of the optical cable, rated tensile strength, and short-circuit current capacity. OPGW is mainly composed of optical units (optical fiber, protective tube) and ground wire units (aluminum-clad steel wire, aluminum alloy. The fibres are loosely buffered in a tube containing an oval, spiralling, holl channel filled with jelly. 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. 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.
