24 Cores OPGW fiber optic cable is a dual-function optical cable that can be used as a ground wire and can be used to transmit voice, video or data signals. UnitekFiber's OPGW cable uses a laser-welded sealed aluminum fiber tube to provide excellent mechanical and thermal protection for the optical fiber, maintaining stable communication performance even in harsh environments. The thick aluminum tube is not only resistant to extrusion, but also significantly improves the fault current rating and enhances the electrical safety of the cable. 24-core OPGW optical cable can be installed on 110KV transmission and distribution lines to transmit voice, data and video communications. OPGW fiber cable uses G652D optical fiber, which can reduce system costs while providing zero dispersion and seamless splicing, reducing splicing losses, and supporting longer fiber runs.
OPGW cables are suitable for overhead transmission lines and have the dual functions of ground wire (used to replace traditional static or shield wires) and communication wires. OPGW cables have the function of "shielded" conductors, which can conduct short-circuit currents and resist lightning strikes, while also providing telecommunications paths for internal and third-party communications. UnitekFiber's OPGW cables are able to withstand the mechanical and environmental stresses (such as those caused by wind or freezing) that overhead optical cables are subjected to. At the same time, they are also able to handle electrical faults on transmission lines, provide a ground path, and prevent damage to the fragile optical fibers inside the cable.
UnitekFiber's OPGW optical cable uses high-quality aluminum tubes. When a short circuit occurs in the circuit, the aluminum tube of OPGW cable can significantly reduce the impact of the current on the optical fiber. The aluminum tube has good conductivity and electromagnetic shielding effect, and it can effectively shunt the short-circuit current and reduce its interference with the optical fiber transmission performance, thereby ensuring that the transmission of optical signals remains stable in the event of a sudden circuit failure, providing a solid guarantee for the continuity of communication.
OPGW cable features 24 cores of single-mode (SM) optical fibers. The fibers adhere to the G652D standard, which is widely used for long-distance communication due to its low attenuation and compatibility with various transmission systems.
The aluminum tube jacket serves as a robust protective layer. It shields the optical fibers from mechanical damage, moisture, and environmental stress (such as temperature fluctuations). Additionally, aluminum provides good electrical conductivity, enhancing the cable's grounding performance in 110kV applications.
Yes, this cable is engineered for 110kV power lines, with specifications optimized for the electrical and mechanical demands of this voltage class. While it may not be suitable for significantly higher voltages (e.g., 220kV or 500kV) without modifications, it could potentially be adapted for lower voltages, though it’s best to consult technical guidelines for specific applications.
Single-mode G652D fibers offer several benefits: they support higher bandwidth over longer distances compared to multi-mode fibers, have lower signal loss (attenuation), and are compatible with most modern optical communication equipment. This makes them ideal for transmitting data, voice, and control signals across power grids.
Yes, the 24 individual cores allow for parallel transmission of multiple signals. Each core can carry separate data streams (e.g., telemetry, SCADA, voice, or video), enabling versatile communication within the power grid without interference between cores.
