Self-supporting opticalcable bird prevention method

Abstract

The invention relates to a self-supporting optical cable bird prevention method and a special shield structure, and belongs to the technical field of electric power communication optical cables. The method comprises the technical scheme that a twisted wire bundle (2) is a twisted-pair cable formed by coiling a plurality of twisted wires, is arranged at two sides of a hanging point, and matched with an ADSS (all-dielectric self-supporting) optical cable (1); a shield (3) is a semi-arc shield made of a polyethylene material with the smooth surface, the length of the shield is matched with that of the twisted wire bundle on the ADSS optical cable; on the tail end of the twisted wire bundle on the ADSS optical cable 10cm of the twisted wires are rolled and forms a 90-degree angle with the twisted wire bundle, so that a bird is prevented from standing on and edge of the twisted wire bundle or pecking the optical cable; two holes (4) are formed respectively in two ends of the shield, and two twisted wires respectively penetrates through the two holes in the ends, and the shield is fixed on the twisted wire bundle by the two twisted wires; and the twisted wires at one end, in which the twisted wire bundle is connected with an armor clamp, are fixed on the optical cable, and the shield is fixed at the end through the two twisted wires, so that the shield is prevented from rotating, two ends of the twisted wires can be protected, and the communication failure caused by the woodpecker pecked optical cable can be prevented.

Description

Technical field [0001] The invention relates to a self-supporting optical cable bird prevention method, which belongs to the technical field of power communication optical cable protection. Background technique [0002] In recent years, power communication optical cables have been frequently interrupted and malfunctioned due to bird pecking. Because the bird peck broken fiber optic cable is difficult to find on the ground, it is very difficult to find the fault point during the rush to repair the communication line. Only after the instrument is used to measure and locate, the fault point can be determined manually. In particular, many power communication optical cables use self-supporting (ADSS) optical cables, which can only be replaced in sections, which not only increases the difficulty of maintenance, but also causes great economic losses. [0003] After several years of research, it has been found that the areas where bird pecks cause communication interruption are mainly in ...

Because it is difficult to find the fault of the bird pecking off the optical cable on the ground, it is very difficult to find the fault point in the process of repairing the communication line.

In particular, many power communication optical cables use self-supporting (ADSS) optical cables, which can only be replaced in sections, which not only increases the difficulty of maintenance, but also causes great economic losses
