ADSS fiber optic cable Shandong anti electric trace multi specification 24 core ADSS single-mode signal fiber optic cable manufacturer

Description :

　　ADSS optical cable parameter performance:

　　The working performance of ADSS optical cable is different from that of ordinary optical cable. This type of optical cable is used for overhead power and works between two power towers or poles, always in an overhead state, with a general span of

　　Between a span of 100-1000 meters, there are also special circumstances where the design institute has a larger span, mainly depending on the needs of the line,

　　ADSS optical cable, also known as overhead power cable, is completely different from ordinary overhead optical cable. Ordinary overhead optical cable is used in local areas of urban communities,

　　ADSS overhead optical cable is specifically designed for use on power towers in large power grids.

　　ADSS optical cables have much stricter requirements than ordinary optical cables, and the breaking force and tensile strength must meet the requirements. The use environment is harsh, so they are subjected to relatively high tension.

　　Rated tensile strength, also known as ultimate tensile strength or breaking force, refers to the calculated value of the sum of the strength of the load-bearing cross-sectional area.

　　For the fiber optic cable profession, if the ratio of RTS/MAT (equivalent to the safety factor K of overhead lines) is inappropriate, even if a lot of spinning fibers are used and the available fiber strain range is narrow, the economic/technical performance ratio will be poor.

　　ADSS structural features:

　　Special power system design is an overhead fully insulated dielectric self-supporting optical cable, which is a non-metallic optical cable with relatively high tensile strength and does not contain any metals.

　　The expansion coefficient of ADSS optical cable is relatively small, and the curvature of the optical cable line decreases as the temperature increases. It is lighter than metal optical cable and easier to use.

　　The service life of ADSS optical cable is relatively long, and the sheath made of AT sheath material has good lightning resistance. Its ice and wind load are also relatively small.

　　ADSS optical cables are installed on high-voltage transmission lines, with a general lifespan of over 25 years. There are many factors that affect their lifespan, including:

　　(1) The gradient of the high-voltage induced electric field near the tower varies greatly, and the high-voltage induced electric field has strong electrical corrosion on the optical cable. Therefore, PE type sheaths are generally used for overhead power lines of 35KV and below,

　　AT type sheath is used for 110KV and above lines;
