Abnormal-shape filling rope for optical cable, cable, photoelectric composite cable or photoelectric comprehensive cable

Abstract

The invention belongs to the technical field of a wire material and relates to an abnormal-shape filling rope for an optical cable, a cable, a photoelectric composite cable or a photoelectric comprehensive cable. The abnormal-shape filling rope comprises a rope body, wherein the rope body is composed of four cylindrical arcs, the other end of a first cylindrical arc is connected with one end of a third cylindrical arc, the other end of the third cylindrical arc is connected with one end of a second cylindrical arc, one end of a fourth cylindrical arc is connected with one end of the first cylindrical arc, and the other end of the fourth cylindrical arc is connected with the other end of the second cylindrical arc; the first, second, third and fourth cylindrical arcs are bent along the same direction; the first / second cylindrical arc are equal in diameter and arc length; the arc length of the third cylindrical arc is no less than 2 / 3 of the circumference of the circle corresponding to the arc and no more than 4 / 5 of the circumference of the circle corresponding to the arc. The rope body is manufactured by a special method. The abnormal-shape filling rope is simple in structure, easy to manufacture and excellent in performance.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and in particular relates to a special-shaped filling rope for an optical cable or a cable or a photoelectric composite cable or a photoelectric composite cable. Background technique [0002] With the rapid development of the communication industry, the application of optical fiber cables and wires and cables is increasing. The use of photoelectric composite cables can make electricity and light directly enter the home, and operators do not need to apply for additional power loads. Therefore, they are more and more favored by operators. However, the existing photoelectric composite cable mainly has the following problems: (1) When the outer gap between the adjacent conductors is large, in order to make the composite cable round and round, the loose tube for containing the optical fiber also needs to be made into a large size. Increased cost; (2) The wire and the loose tube are stranded ...

Problems solved by technology

However, the existing photoelectric composite cables mainly have the following problems: (1) When the outer gap between the adjacent conductors is large, in order to make the composite cable round and round, the loose tube that accommodates the optical fiber also needs to be made into a large size. Increased cost; (2) The wire and the loose tube are twisted to form a cable core, and the outside of the cable core is wrapped with a yarn-like substance, which is easy to damage the loose tube, causing abnormal optical signal transmission, and when the temperature changes significantly, the wrapping The substance damages the loose tube, thereby affecting optical communication, and the dressing material itself is expensive; (3) It is not easy to remove the loose tube by twisting the wire and the loose tube, and the dressing material needs to be cut before taking it out. It is easy to damage the cable core, and it is not easy to restore; and it is very troublesome to take out the loose tube

The filling rope used in the prior art has poor acid and alkali resistance and oil resistance, and the water absorption resistance is not ideal, and the processing performance and toughness need to be improved.
