An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire.

As of recent market analysis, the price range for OPGW cables is generally between RMB 10,000 to RMB 30,000 per kilometer. It is constructed with optical fibers laid within an aluminum and steel alloy structure of wire. While the outer layers of the wire provide mechanical support and grounding to the power system, the inner fibers facilitate high-speed communication of data. Apart from functions as a conventional ground wire, to protect the transmission line from lighting and short circuit current, OPGW also provide a data communication channel with the optic fiber inside the cable. The Central Tube Optical Ground Wire (OPGW) is surrounded by single or double layers of aluminum clad steel wires (ACS) or mix ACS wires and aluminum alloy wires, 24 Core OPGW Cable design is fully adapted to the most common electric line needs.

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. The most important types of these cables are OPGW (Optical Power Ground Wire), OPPC (Optical Phase Conductor), ADSS (All-Dielectric Self-Supporting) and SkyWrap. OPGW cables combine the functions of grounding and communication, with a optical fibers in the middle of the conductive cable. Market Scope: The research covers the OPGW splicing ecosystem, including high-voltage transmission line. OPGW cable fusion splicing is a meticulous job, especially in the end face preparation, fusion splicing, fiber coiling and other links, which require the operator to observe carefully, consider carefully and operate in accordance with the specifications. By using extension collars and/or splice trays for fibre ribbons, the splicing capacity can be i ree or four cable entrances.
