ADSS fiber optic cable that is fully self-supporting optical cable. The utility model has the advantages of light weight, small outer diameter, large span of installation, anti-thunder strike, no electromagnetic interference, easy laying and the like, and can use the existing power lines to fully utilize the tower resources and greatly save the project investment cost. Therefore, much favored by the power sector in recent years has been widely used in the power system.
ADSS cable design life is usually more than 20 years, and its use of the environment is very harsh and complex, first of its high-voltage lines with the laying of the same tower, long-term operation in the vicinity of high voltage transmission lines, there is a strong electric field around, coupled with moisture and Cable jacket surface contamination under the action of the electric field, so that the outer sheath of ADSS cable easily damaged by electric erosion, which not only to withstand the above described corrosion, but also to withstand a variety of mechanical stress (gravity , Snow load and wind vibration), rain, humidity, air pollution, ultraviolet radiation.
The above reasons can cause serious damage to the jacket material, so the material not only has excellent resistance to tracking, but also should have excellent resistance to UV radiation, environmental stress cracking resistance and other mechanical and physical properties . Therefore, the selection of ADSS fiber optic cable sheathing material is particularly important, its resistance to the performance of sheath material directly determines the merits of ADSS cable life.
