This article discusses the significant specifications of ADSS fiber optic cables, providing information about its structural features, mechanical performance, optical control, and environmental tolerability. AFL-ADSS® (All-Dielectric Self-Supporting) fiber optic cable is a non-metallic cable which supports its own weight without the use of lashing wires or messenger cables. They are adopted widely because they are made of fully dielectrics, are relatively lightweight, and can be installed even without conducting. The“All Dielectric Self-supporting (ADSS)”cables are designed for aerial self supporting application at short,medium and long span distances. Adopted for high voltage,middle,small span conditions in Power Transmission Systerm or mazy terrain such as river spanning,mountains1.
