Installation and Design of OPGW The installation of OPGW involves placing it on the topmost positions of power transmission towers alongside high-voltage conductors. Designed to be durable and reliable, OPGW is engineered to withstand harsh environmental conditions, including extreme weather and physical stress. opgw The construction of OPGW typically consists of a combination of aluminum and steel for strength, with optical fibers housed in the center or core of the wire. Its design ensures that it functions both as a lightning protection conductor and as a medium for high-speed data transmission. Proper installation and maintenance are essential for maximizing its performance and longevity.
