Problems solved by technology

[0003] However, due to the small tensile force and low strength of aluminum, for copper-clad aluminum conductors with small diameters or small amounts of copper, the copper-clad aluminum conductors are easily broken and the processing difficulty is significantly increased, or even impossible to process.
However, if the diameter is increased or the amount of copper used is increased, the cable will be hardened, which is not conducive to laying

Embodiment Construction

[0053] for figure 1 The copper-clad aluminum three-core round flame-retardant and fire-resistant flexible cable of the present invention shown, the method for manufacturing the cable includes: the step of making the copper-clad aluminum wire into a single conductive core 1; The step of forming the wire core refractory layer (2, 3) on the outer surface; the insulation treatment step of extruding insulating material on the wire core refractory layer (2, 3) to form an insulated wire core with an insulating layer 4; for three The step of cable-forming the insulated wire core with the insulating layer 4 to form a cable; and the step of extruding refractory plastic on the cable to form a flame-retardant sheath layer 6 . Since the cross-section of the single conductive core 1 is usually circular when manufacturing a single conductive core 1, it is usually not necessary to process the conductive core 1 into a circular conductive core 1. ; But if the cross-section of the single conduc...

Abstract

The invention discloses a copper-clad aluminum three-core flame retardant and fire resisting flexible cable and a manufacturing method thereof. The method comprises the steps that: a copper-clad aluminum conductor is made into a single conductive wire core; the single conductive wire core is processed into a conductive wire core provided with the section of a fan shape; a wire core fire resisting layer is formed on the outer surface of the conductive wire core provided with the section of the fan shape; an insulation material is extruded on the wire core fire resisting layer, and an insulation process for forming an insulation wire core provided with an insulation layer is carried out; a cable-froming process is carried out to three insulation wire cores provided with insulation layers, thereby forming a cable yarn; flame retardant plastic is extruded on the cable yarn so as to form a flame retardant restrictive coating. The cable of the invention has the advantages of low copper consumption, light weight and low cost.

Description

technical field [0001] The invention relates to wire and cable technology, in particular to a copper-clad aluminum three-core flame-retardant and fire-resistant flexible cable and a manufacturing method thereof. Background technique [0002] For the concept of copper-clad aluminum, wire and cable manufacturers are no strangers, that is, the structure of each conductive monofilament that constitutes the conductive core is processed into the outer layer of copper and the inner layer of aluminum, which can save a lot of belongings. Copper, a strategic resource, can make copper play its biggest role. In the literature such as Chinese patent literature, there are many reports in the past, such as: the copper-clad aluminum communication cable introduced by the Chinese patent authorization announcement number CN2881898, the copper-clad aluminum data communication cable disclosed by CN2881899, and the copper-clad aluminum conductor communication cable recommended by CN200979818Y , ...
