The key parameters, as operating voltage, nominal tensile strength, the maximum allowable stress and the annual average stress, must be understood and carefully considered when selecting the appropriate cable. ADSS Fiber Optic Cable work in a large-span two-point support (usually hundreds of meters, or even more than 1 km) overhead state, completely different from the traditional concept of overhead (post and telecommunications standard overhead hanging wire hook program, an average of 0. 4 meters for the. Micromodule: thin wall flexible tubing, FlexTube®, filled with a suitable compound, housing the single-mode optical fibres. The fibres inside the tubes can be accessed without the need of any specific tool. Longitudinal Water Tightness: water swellable materials (dry core). Peripheral Strength. ADSS (All-Dielectric Self-Supporting) fiber optic cables are specifically produced for elevated applications in electric power transmission and distribution. 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.
