This variant of OPGW cable integrates advanced materials and construction techniques to provide robust mechanical strength, exceptional electrical conductivity, and reliable data transmission capabilities.

Overview of Central AL-covered Stainless Steel Tube OPGW Cable:

Central AL-covered Stainless Steel Tube OPGW Cable is engineered to serve as both a grounding element for the power system and a conduit for high-speed data transmission. It consists of a central stainless steel tube encased in aluminum, which houses optical fibers for communication purposes. This design ensures optimal performance in diverse environmental conditions and applications.

Construction of Central AL-covered Stainless Steel Tube OPGW Cable:

1. Central Stainless Steel Tube: The core of the cable comprises a helically stranded stainless steel tube, providing superior mechanical strength and resistance to external stresses. This stainless steel tube serves as the primary structural component, offering protection to the optical fibers housed within and ensuring the integrity of the cable under tension and environmental factors.
2. Aluminum Coating: The stainless steel tube is covered with a layer of aluminum, enhancing electrical conductivity and providing additional protection against corrosion. The aluminum coating also contributes to the grounding function of the cable, ensuring efficient dissipation of electrical currents and minimizing electromagnetic interference.
3. Optical Fibers: Multiple optical fibers are housed within the central stainless steel tube, enabling high-speed data transmission over long distances. These optical fibers are typically made of silica or other glass compositions, offering low attenuation and high bandwidth for various communication applications.
4. Buffer Tubes: Optical fibers are organized within buffer tubes, which serve to protect them from moisture, abrasion, and mechanical stresses. Buffer tubes help maintain the integrity and reliability of the optical fibers, ensuring consistent performance over the lifespan of the cable.
5. Filling Compound: The interstices between the buffer tubes and the stainless steel tube are filled with a water-blocking compound to prevent moisture ingress and ensure the longevity of the cable.
