To effectively splice OPGW cables, begin by ensuring site safety through the establishment of an equal potential zone, then prepare and straighten the cable, remove the armor to access the fibers, splice the fibers using a fusion splicer, and secure the splice with a heat shrink. To effectively splice OPGW cables, begin by ensuring site safety through the establishment of an equal potential zone, then prepare and straighten the cable, remove the armor to access the fibers, splice the fibers using a fusion splicer, and secure the splice with a heat shrink. OPGW cables combine the functions of grounding and communication, with a optical fibers in the middle of the conductive cable. OPGW cables are installed on transmission and distribution power lines, above the high-voltage power conductors since acts as the protection from lightning strikes. Careful. This experience allows Zhongtian Hitachi offering our customers a broad range of installation services, covering from supervision and commissioning to full turn-key operations. Our field specialist will arrive on site and provide supervision to staff directly involved in the installation process. Abstract – Fiber-optic cables are used in many different applications, from Local Area Networks (LANs) to Wide Area Networks (WANs). Quality during Coiling of OPGW near Joint.
