1. Precisely controlled fiber excess length ensures excellent mechanical and temperature performance.
2. The loose tube material itself exhibits high hydrolysis resistance and superior strength.
3. Filled with specialized thixotropic gel, providing critical protection to the fibers.
4. Good lateral crush resistance and flexibility.
5. A layer of helically wrapped FRP ensures tensile strength and provides effective protection to the loose tube.
6. Helically wrapped FRP and FRP tape armor provide excellent rodent resistance.
7. The polyethylene (PE) sheath offers excellent UV radiation resistance.
8. Small diameter, light weight, and easy installation.
9. All-dielectric cable design requires no grounding and is lightning strike resistant.
