All Dielectric Self-Supporting ADSS Fiber Optic Cable 2-144 Core
DESCRIPTION
FEATURES
1. Designed for power system, fully insulated medium, self-supporting overhead optical cable can be directly hung on the power pole tower;
2. Fully-insulated structure and high withstand voltage index, which is convenient for the installation of overhead power lines for live operation;
3. The FRP with high tensile strength can withstand strong tension and achieve a large span, while preventing bird pecking and artificial shooting;
4. The thermal expansion coefficient of the ADSS optical cable is small. When the temperature changes greatly, the arc of the optical cable line changes very little, and its weight is light, and its ice crawling and wind load are also small.
