Abstract

The invention discloses a composite cable. The composite cable comprises a sheath and a cable core, wherein the cable core comprises a conductor, the surface of the conductor is coated with a graphenelayer, the periphery of the conductor is coated with a shielding layer, the surface of the shielding layer is provided with a woven mesh layer, and the surface of the woven mesh layer is provided with an insulating layer; filling materials are filled between the inner wall of the shielding layer and the surface of the graphene layer, and the surface of the cable core is wrapped with a shielding protection net. According to the composite cable and the preparation process thereof, through the arrangement of the graphene layer, the strength of the cable can be greatly enhanced, the service lifeof the cable is prolonged, the signal stability of the cable is maintained, unnecessary loss is avoided, the fireproof performance is relatively high, and if the internal temperature of the cable is too high, the probability of fire disasters is reduced; and torsion resistance of the cable is relatively high, so when the cable is twisted, the internal cable core cannot be broken, and normal communication can be maintained.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a composite cable and a preparation process thereof. Background technique [0002] Wires and cables refer to materials used for power, electricity and related transmission purposes. There is no strict boundary between "wires" and "cables". Usually, products with a small number of cores, a small product diameter, and a simple structure are called wires, without insulation. It is called bare wire, and others are called cables; those with larger conductor cross-sectional area (greater than 6 square millimeters) are called large cables, and smaller ones (less than or equal to 6 square millimeters) are called small wires, also known as cloth wires. The rubber cable is suitable for power transmission lines for fixed laying of AC rated voltage 0.6 / 1KV and below or connecting cables for mobile appliances. The product has the characteristics of heat radiation resistance, cold res...
