Problems solved by technology

[0002] Multi-core wires and cables are used to transmit alternating current or used as communication lines. The metal cores of the commonly used multi-core wires and cables are usually circular conductors, and the multi-core wires and cables are composed of multiple round conductors. Increasing the number of circular conductors leads to an increase in the diameter of the cable and an increase in the overall cost of the multi-core wire and cable
Moreover, the number of conductors of multi-core wire and cable is large, resulting in poor heat resistance

Embodiment Construction

[0014] Such as figure 1 as shown, figure 1 It is a schematic cross-sectional view of a multi-core wire and cable proposed by the present invention.

[0015] refer to figure 1 , a multi-core wire and cable proposed by the present invention, which includes a plurality of elliptical conductors 2 and sheaths 4 . A wire and cable composed of a plurality of elliptical conductors 2 has a large surface and a correspondingly increased current carrying capacity; the periphery of the sheath 4 is provided with a wrinkled texture 5 that facilitates high-temperature heat dissipation and is used to increase the surface area of ​​the sheath 4 , the increased surface area is conducive to the outward diffusion of heat generated by the current carrying capacity of the power transmission, accelerating the heat exchange between heat and air, which is conducive to the high-temperature heat dissipation of multi-core wires and cables, and enhancing the heat resistance of wires and cables.

Abstract

The invention discloses a multi-core cable which comprises a plurality of oval conductors and a protection sheath. Wrinkle textures facilitating high temperature radiation are arranged at the periphery of the protection sheath. The multi-core cable comprises the oval conductors and the protection sheath. The multi-core cable composed of the oval conductors is large in surface to correspondingly improve power transmission carrying capacity. The wrinkle textures facilitating high temperature radiation are arranged at the periphery of the protection sheath, so that the surface area of the protection sheath is enlarged, high temperature radiation of the multi-core cable is facilitated, and the heat resistance of the multi-core cable is enhanced.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a multi-core wires and cables. Background technique [0002] Multi-core wires and cables are used to transmit alternating current or used as communication lines. The metal cores of the commonly used multi-core wires and cables are usually circular conductors, and the multi-core wires and cables are composed of multiple round conductors. Increasing the number of circular conductors leads to an increase in the diameter of the cable and an increase in the overall cost of the multi-core wire and cable. Moreover, the number of conductors of multi-core wire and cable is large, resulting in poor heat resistance. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a multi-core high-temperature-resistant wire and cable with more carrying capacity and better heat resistance. [0004] The inven...
