Problems solved by technology

[0002] Existing cables generally include an outer sheath layer and an inner sheath from the outside to the inside, and the inner sheath is wrapped with a core wire, and the core wire includes optical cables and cables, etc., between the outer sheath layer and the inner sheath A reinforcement layer is also provided to improve the tensile strength and flame retardancy of the cable. However, the existing reinforcement layer is usually composed of aramid fiber. When the cable is exposed to the air for a long time, the aramid fiber reinforcement layer is prone to damage. Aging makes the cable easy to tear under the action of external force, and the tensile strength is low, which shortens the service life of the cable

Abstract

The invention provides a cable, and belongs to the technical field of cables. The cable solves the problem of low tensile strength of the existing cable. The cable comprises an inner sheath; a plurality of wire cables are annularly arranged in the inner sheath; an outer sheath is arranged on the inner sheath; a reinforcing layer is arranged between the outer sheath and the inner sheath; the reinforcing layer comprises at least one reinforcing rib; the inner sheath is wrapped with the reinforcing rib, and the reinforcing rib is in contact with the inner sheath and the outer sheath, wherein the reinforcing rib is made from a manganese iron alloy; and the manganese iron alloy comprises the following components in parts by weight: 100-300 parts of iron, 200-500 parts of manganese, 50-80 parts of silicon, 20-30 parts of carbon, 20-30 parts of titanium carbide, 10-20 parts of molybdenum, 5-10 parts of scandium and 5-10 parts of lanthanum. The cable has the advantages of high tensile strength and long service life.

Description

technical field [0001] The invention belongs to the technical field of cables, and relates to a cable. Background technique [0002] Existing cables generally include an outer sheath layer and an inner sheath from the outside to the inside. The inner sheath is wrapped with a core wire, and the core wire includes optical cables and cable wires, etc., between the outer sheath layer and the inner sheath. A reinforcing layer is also provided to improve the tensile strength and flame retardant performance of the cable, but the existing reinforcing layer is usually composed of aramid fibers. When the cable is exposed to the air for a long time, the aramid fiber reinforcing layer is prone to occur. Aging makes the cable easy to tear under the action of external force, and the tensile strength is low, which shortens the service life of the cable. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a cable with high tensile strength and long servic...
