All dielectric self-supporting aerial installation cable-ADSS Double Layer Aerial ADSS Cable is used for communication cable of overhead high-voltage electricity transmission system,it also can be used as communication cable at the areas where lighting is frequent or distance is big. Characteristic: 1.Two jacket and stranded loose tube design,stable performance and compatibility with all common fiber types. 2.Instead of aramid yarn or glass yarn,there is no support or messenger wire required,aramid yarn is used as the strength member to assure the tensile and strain performance. 3.Mainly installed at existing 220KV or lower voltage power lines.
