Wirenet 2-288 Core Double Jacket ADSS Fiber Optical Cable
Wirenet 2-288 Core Double Jacket ADSS Fiber Optical Cable
Â
No metal wires are used in an ADSS cable. Optical fibers are either supported in loose buffer tubes, or arranged in a ribbon configuration. To prevent strain on the fibers, most types provide the fibres with excess slack length compared to the length of the supporting member.
For longer spans, the most common design gets its strength from aramid fiber yarns, which are coated to prevent water wicking. The aramid yarn strength member surrounds a core made up of multiple buffer tubes, each containing multiple fibers, all surrounding a plastic core.[4][5][6][7] The outer sheath provides protection from water and sunlight. Another version consists of a large central tube containing multiple flat, thin structures called fiber ribbons; these consists of 6 or 12 fibers laminated between layers of a tape-like material.
Features:
Can be installed without shutting off the power
Light weight and small diameter reducing the load caused by ice and wind and the load on towers and backprops
Large span lengths
Good performance of tensile strength and temperature
The design life span is 30 years
