ADSS optical cable introduction:
ADSS optical cable is also called all-dielectric self-supporting optical cable. All-dielectric means that the optical cable uses all-dielectric materials. Self-supporting refers to the self-supporting member of the optical cable can withstand its own weight and external load. This name clearly shows the use environment and key technology of this optical cable: because it is self-supporting, its mechanical strength is important; the use of all-dielectric materials is because the optical cable is in a high-voltage strong electric environment and must be able to withstand strong electricity Impact; because it is used overhead on a power tower, there must be a matching pendant to fix the optical cable on the tower. That is, there are three key technologies for ADSS optical cable: mechanical design of optical cable, determination of suspension point and selection and installation of matching fittings.
ADSS optical cable characteristics:
ADSS optical cable has a different structure from the overhead conductor, its tensile strength is borne by aramid rope, the elastic modulus of aramid rope is more than half smaller than steel, and the coefficient of thermal expansion is a fraction of steel, which determines the arc of ADSS cable Sags are more sensitive to changes in external loads. Under ice coating, the elongation of the ADSS cable can reach 0.6%, while the wire is only 0.1%; the sag is relatively slow to temperature changes, and the sag basically remains unchanged when the temperature changes; its wind declination is very high under windy conditions Large, when the wind speed is 30m/s, the wind deflection angle can reach 80°, and the wind deflection angle of the wire is only about half of the optical cable.

The ability to withstand extremely severe weather (high winds, ice, etc.) is strong.

The outer sheath of the ADSS optical cable is made of AT or PE material, which runs in a strong electric field and has problems of electrical corrosion.

ADSS fiber optic cable will generate wind
