ADSS 2-Core Single-Mode Special All-Dielectric Self-Support Aerial
Fiber Optic Cable
ADSS cable for high-voltage transmission lines uses power system poles. Non-metallic, self-supporting, safe, cost-effective, minimizes damage, no interference, suits large spans. Popular in power system urban/rural network transformations.
Features
Optical fiber designs include single-mode, multi-mode, and integrated cable.
The aerodynamic performance of the optical cable is superior due to its sleek shape.
The structure of the all-dielectric optical cable is conducive to installation and maintenance.
With a wide temperature adaptability range and small linear expansion coefficient, it meets the requirements of harsh environments.
The leakage resistance voltage is 25KV.
The optical cable has extremely high tensile strength and anti-elastic properties due to torque balance and aramid winding.
