144 Fiber Core Composite Overhead Fiber Optic Ground Cable Opgw Fiber Optic Cable

OPGW fiber optic cable is a dual-function cable that performs the functions of a grounding cable and also provides a patch for the transmission of voice, video or data signals. Fibers are protected from environmental conditions (lightning, short circuits, charging) to ensure reliability and longevity. The cable is designed to be installed in transmission and distribution lines to carry voice, data and video communications, especially in lighting waveform monitoring system, an observation system for aerial test line, data information system maintenance, power line protection system, power line operation system

(1) The OPGW uses a stainless steel loose tube structure, which increases its reliability and temperature resistance performance.
(2) The OPGW meets the application requirement of large fiber lines.
(3) OPGW are especially applied for optical communication system during the installation of electric transmission line.
(4) Project design (sag voltage calculation, short circuit current, ADSS hardware accessories calculation)

While OPGW is easily installed in new construction, electric utilities find the increased capacity of fiber so useful that techniques have been developed to replace ground wires with OPGW on energized lines. Live line working techniques are used to rewire the towers with OPGW replacing the all-metal type of overhead protection cables.
