8 12 24F SM MM G652D Direct Burial Outdoor Cable GYFTA53
8 12 24F SM MM G652D Direct Burial Outdoor Cable GYFTA53
Description
The fibers, each 250μm, are housed in a loose tube constructed from high modulus plastic, filled with a water-
resistant compound. An FRP (Fiber Reinforced Plastic) serves as the non-metallic strength member at the
core. These tubes, along with fillers, are stranded around the strength member, forming a compact and circular
cable core. To protect against water ingress, an Aluminum Polyethylene Laminate (APL) is applied around the
cable core, followed by a thin PE inner sheath. The tensile strength is enhanced with a layer of kevlar yarn, and
after longitudinally applying PSP (Polyethylene-Stranded Polyethylene), the cable is completed with a PE outer
sheath.
Application
* Adopted to Outdoor Distribution and Direct Burial: Designed for use in outdoor distribution and direct burial
applications, ensuring durability and reliable performance in varied environmental conditions.
* Adopted to Trunk Power Transmission System: Suitable for trunk power transmission systems, providing
efficient and reliable power transmission over longer distances.
* Access Network and Local Network in High Electromagnetic Interfering Places: Ideal for use in access
networks and local networks located in high electromagnetic interfering environments, ensuring stable and
interference-resistant connectivity.
Characteristic
* Good Mechanical and Temperature Performance: Exhibits excellent mechanical strength and temperature
resistance, ensuring reliable performance in various conditions.
* Special Tube Filling Compound Ensuring Critical Fiber Protection: Utilizes a specialized tube filling compo-
und to provide crucial protection to the fibers, enhancing their durability and longevity.
* Crush Resistance and Flexibility: Designed with crush resistance and flexibility, allowing for installation in
challenging environments while maintaining structural integrity.
* PSP Enhancing Moisture-Proof: The inclusion of PSP (Polyethylene-Stranded Polyethylene) enhances
moisture-proof properties, further safeguarding the cable against environmental factors.
