ADSS cable is designed to be hung from overhead utility poles using brackets or other hardware, without the need for additional support. This makes it a popular choice for telecommunications companies and utility providers who need to quickly and easily install fiber optic cable in rural or remote areas.
In order to properly design the structure of the ADSS cable, many aspects must be considered, including mechanical strength, conductor sag, wind speed b ice thickness c temperature d topography, Span, and Voltage.
Usually, when you are in production, you need to consider the following questions.
Jacket Type: AT/PE
PE sheath: ordinary polyethylene sheath. For power lines below 110KV and ≤12KV electric field strength. The cable should be suspended where the electric field strength is small.
AT sheath: anti-tracking sheath. For power lines above 110KV, ≤20KV electric field strength. The cable should be suspended where the electric field strength is small.
Out Cable Dia.:Single Jacket 8mm-12mm; Double jacket 12.5mm-18mm
Fiber Count:4-144Fibers
Aramid Yarn Details: Something like (20*K49 3000D). This main calculation of tensile strength.
RTS: Rated tensile strength
Refers to the calculated value of the strength of the bearing section (mainly counting the spinning fiber).
UTS: Ultimate Tensile Strength UES>60% RTS
In the effective life of the cable, it is possible to exceed the design load when the cable by the maximum tension. That means the cable can be overloaded for a short time.
MAT: Max allowable working tension 40% RTS
MAT is an essential basis for sag-tension-span calculation and necessary evidence to characterize the stress-strain characteristics of ADSS optical cable. Refers to the design of meteorological conditions under the theoretical analysis of the total load and cable tension.
Under this tension, the fiber strain should be no more than 0.05% (laminated) and no more than 0.1% (central pipe) without additional attenuation.
EDS: Every Day Strength (16~25)% RTS
The annual average stress, sometimes called the moderate daily stress, refers to the wind and no ice, and the yearly average temperature, the theoretical calculation of the load cable tension, can be considered the ADSS in the long-term operation of the intermediate pressure (should) force.
EDS is generally (16~25) %RTS.
Under this tension, the fiber should have no strain, no additional attenuation, that is, very stable.
EDS is also the fatigue aging parameter of optical fiber optic cable, according to which the anti-vibration design of optical fiber optic cable is determined.
