Anti-icing tracking resistance ADSS optical cable and manufacturing technology

Abstract

The invention discloses an anti-icing tracking resistance ADSS optical cable and a manufacturing technology. The optical cable comprises a cable core. An inner sheath and an outer sheath are successively arranged outside the cable core. An anti-tensile layer is arranged between the inner sheath and the outer sheath. A first water-blocking type filler is arranged between the cable core and the inner sheath. The outer sheath comprises an outer sheath main body. An external surface of the outer sheath main body is provided with an interacted bulged rib. A loose casing pipe is extruded and molded outside the optical cable so as to form an optical cable unit. A center reinforcement component, a filling rope and the optical cable unit are intertwisted so as to form the cable core. One layer of the inner sheath is extruded and molded outside the cable core. And then, the anti-tensile layer and the outer sheath are successively intertwisted on an outer wall of the inner sheath. The optical cable possesses good electric leakage resistance performance, can bear a strong electric field, have a long service life, and possesses stable light transmission performance and a snow prevention characteristic.

Description

technical field [0001] The invention relates to an ADSS optical cable, in particular to an anti-icing anti-electric tracking ADSS optical cable and a preparation process thereof. Background technique [0002] With the advent of the information age, the amount of information transmitted has exploded. As an effective means of large-capacity and long-distance transmission, fiber optic cables have been widely used, and the growth rate is amazing. Since the optical cable is erected indoors and outdoors, it is required that the optical cable must withstand the test of the harsh environment, especially in snowy days, the snow on the optical cable is very easy to generate, which will not only increase the bearing weight of the optical cable, cause the optical cable to break, but also damage the optical cable due to snow accumulation , making the leakage resistance performance of the optical cable drop rapidly. At the same time, because the optical cable needs to withstand the elec...

AI Technical Summary

Problems solved by technology

Since the optical cable is erected indoors and outdoors, it is required that the optical cable must withstand the test of the harsh environment, especially in snowy days, the snow on the optical cable is very easy to generate, which will not only increase the bearing weight of the optical cable, cause the optical cable to break, but also damage the optical cable due to snow accumulation , making the leakage resistance performance of the optical cable drop sharply

At the same time, because the optical cable needs to withstand the electric field generated by a higher voltage during transmission, the existing optical cable is extremely vulnerable to damage, resulting in leakage and other phenomena, which seriously shortens the service life of the optical cable, resulting in poor communication
