UnitekFiber's 12 cores OPGW Fiber Optic Ground Wire is engineered for 35kV, 110kV, 220kV, 500kV, 750kV or more overhead high voltage transmission systems, combining reliable communication and overhead grounding. Featuring a stainless steel central loose tube, the OPGW fiber optic cable ensures robust protection for the enclosed fibers. Inside, premium G655D single-mode fibers deliver exceptional transmission performance, ideal for high-speed, long-distance signals. Encased in an aluminum-clad steel wire outer sheath, the cable balances strength and lightweight design, with a small cable diameter that simplifies installation. Specifically designed for overhead mounting, it withstands harsh outdoor conditions, making it a trusted choice for power grid communication infrastructure.
The steel central loose tube serves as the core protective structure of 12 cores OPGW cable, offering superior corrosion resistance and mechanical strength. Steel Central Loose Tube of OPGW fiber optic cable withstands extreme weather conditions, including high humidity, salt spray, and temperature fluctuations, ensuring long-term stability for the enclosed fibers. The optical ground wire with its robust construction prevents external pressure and impact from damaging the delicate optical components, making the cable highly durable in harsh outdoor environments.
12Core OPGW fiber cable is using Aluminum-clad steel wire outer sheath, which provides a perfect balance of strength and lightweight design. Aluminum-clad steel wire of OPGW wire offers high tensile strength, ensuring the fiber optical cable can withstand the stresses of overhead installation and harsh weather. The aluminum cladding adds corrosion resistance, protecting the underlying steel and enhancing the fiber optical cable's durability. This combination makes OPGW fiber optical cable both strong and lightweight, facilitating easy installation and reducing the load on supporting structures.
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.
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.
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.
We installed this 24core OPGW cable during a 110kV grid upgrade last year, and it’s been exceptional. The aluminum tube jacket held up perfectly through heavy rain and extreme temperature swings. The G652D fibers deliver consistent signal quality—our SCADA and telemetry systems run flawlessly.
