STRUCTURE
The Optical Ground Wire (OPGW) cable is a state-of-the-art solution designed to serve dual purposes of grounding and communication for high-voltage transmission lines. An OPGW cable combines the functionalities of a traditional ground wire with the capabilities of fiber optic communication, making it an essential component in modern power grid infrastructure.
FEATURES & SPECIFICATION
What Are the Features of OPGW Cable ?
- Excellent corrosion resistant performance.opgw cable
- Applicable to coastal areas and areas with heavy pollution.optical ground wire
- Easy splice fiber of code color opgw fiber cable
- Fiber optic cable (OPGW-2S 1/24D1 (74/52-111/0)
- OPGW Earth Wire must be capable of withstanding the mechanical stresses applied to overhead cables by environmental factors like wind and ice, as well as handling electrical faults on the transmission line without damaging the optical fibers.
- The OPGW cable is constructed with high-tensile strength materials, ensuring it can withstand extreme weather conditions and mechanical stress. This durability ensures the reliability and longevity of the cable, reducing maintenance costs and downtime.
- The OPGW cable serves as both a grounding wire and a communication channel. This dual functionality not only saves on installation costs but also maximizes the use of infrastructure space. By combining these two essential functions, the OPGW cable becomes a cost-effective solution for power companies.

What Are the Advantages of Using 48core OPGW Fiber Cable?
The advantages of using 48 core OPGW fiber cable are numerous and include high-quality signal transmission, anti-electromagnetic interference, longer operating life, integration with the ground wire in the power network, and good security. These cables are widely used in transmission networks of various voltage levels and are known for their low transmission signal loss and high communication quality. They can be installed on the top of the transmission line tower without considering the best frame hanging position and electromagnetic corrosion problems. Additionally, 48 core OPGW fiber cables are integrated with the ground wire in the power network, avoiding the huge cost of repeated construction and maintenance. They are also less prone to theft, cutting, and destructive attacks, making them a secure choice for power transmission networks.
