Reliable, self-support cable for overhead installations. 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, typically installed in overhead applications along power distribution or transmission rights-of-way. The use of aramid yarns allows. Experience uninterrupted connectivity with our ADSS (All Dielectric Self Supporting) cables. One of the identification or selection methods is defined by the voltage level to which they will be subjected and/or the wind speed they will be able to withstand. As its name indicates, there are no metallic components and the cable does not require a support or messenger wire.
