Purpose: To measure the fiber optic characteristics and locate faults, splices, and other events along the cable. Launch a test pulse and analyze the reflected signals. To help you understand these methods better, I have organized this section into several detailed subsections. OPGW must also be capable of handling electrical faults on the transmission line by providing a path to ground without damaging the sensitive optical fibers inside. ngths2. Optical fibers, which serve as the dielectric core of an OPGW, a e shielde by an aluminium tube and d rushing, bending, twisting, tensile stress, and moisture by the central fiber optic unit. Together, the. 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. Testing an Optical Ground Wire (OPGW) cable is crucial to ensure its integrity and performance, particularly because it combines the functions of grounding and optical communication. Visual Inspection Purpose: To detect any physical damage. This specification covers Optical Ground Wire Cables (OPGW) for the installation on high voltage overhead power lines. The specification describes the basic design of an.
