ADSS cable is a fully dielectric (non-metallic) self-supporting aerial fiber cable designed for installation on power transmission towers and distribution poles. This guide. ADSS large span design is a specialized discipline: Key Takeaway: For ADSS cable spans exceeding 1000 meters — common in river crossings, valley spans, and highway flyovers — the governing design parameters are MAT (Maximum Allowable Tension) and Sag. Planning for proper clearances requires knowing the “sag” characteristics of the proposed installation. 2 The cable shall be used for aerial install levant IEC, ITU-T and EIA Recommendation or bette ha 25 years without any at en ar ing can be changed w ted by a metal cover firmly secured to the flange. A minimum ends with red and green adhesive cap respectively. Discover today with a few simple steps!In this webinar we will discuss how to obtain the sag and tension data that you need for your project. Computer programs, in particular PLS-CADD.
