Drawings
The structure of the present invention and its advantageous technical effects will be described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a radial cross-sectional view of a hybrid wire of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantageous technical effects of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is presented herein for purposes of illustration only and is not intended to limit the invention.
Referring to fig. 1, the hybrid electric wire of the embodiment includes an insulating sheath 3 and a wire core, the wire core includes a copper core 1 and a copper alloy core 2, the copper core 1 and the copper alloy core 2 are twisted together, an outer sheath 4 is further disposed outside the insulating sheath 3, and the outer sheath 4 includes a fireproof layer, a waterproof layer and an anti-aging layer. Wherein the number of the copper cores is one or more, and the number of the copper alloy cores is 1 or more. The metal copper in the wire core can be 90-96% in percentage by mass, and the other metal can be 10-4%; preferably, in this embodiment, the metallic copper is 91% and the other metals are 9%; other metal components in the copper alloy core can be selected according to the application environment, such as metal silver can be added for improving the hardness, and metal iron can be added for improving the strength; preferably, the copper alloy core of the embodiment is a copper-aluminum alloy core, so that the density is reduced, and the electric wire conductivity can reach the standard through the wire diameters of the copper-aluminum alloy and the copper core.
The manufacturing process of the hybrid electric wire of the embodiment includes three steps:
1. drawing
The copper core and the copper alloy core of this embodiment are respectively processed and drawn into copper core conductors having different sectional areas and sizes by monofilament drawing.
At normal temperature, the drawn copper core and copper alloy core have reduced sectional area, increased length and improved strength through one or more die holes of the drawing die by using a wire drawing machine. This process is the first process of wire and cable production and is of great importance.
2. Twisting
The drawn copper core and copper alloy core are interwoven and wound according to the specified requirement and the specified direction, and the twisting process can be divided into: conductor twisting, cabling, braiding, wire armouring and winding.
In order to reduce the cost of the electric wire and the cable, the electric wire and the cable are convenient to lay and install, the wire core is formed by twisting a plurality of monofilaments, wherein 13 copper cores and 3 copper alloy cores are combined into 16 single cores, so that the material composition is reduced.
3. Coating
According to different performance requirements and use environment requirements of different wires and cables, insulating materials are coated outside the conductors through special equipment, so that the use performance and safety of the wires are enhanced.
The outer jacket is a structural part that protects the insulation of the wire and cable from environmental elements. The main function of the outer sheath is to improve the mechanical strength of the wire and cable, and the ability of chemical corrosion resistance, moisture resistance, water immersion resistance, cable combustion resistance and the like. And directly extruding and wrapping the plastic sheath by using an extruder according to different requirements on the cable.
Modifications and variations of the above embodiments will be apparent to those skilled in the art in light of the above teachings. Therefore, the invention is not limited to the specific embodiments disclosed and described above, but some modifications and changes of the invention should be also included in the scope of the claims of the invention. In addition, although specific terms are used in the present specification, these terms are for convenience of description only and do not limit the present invention in any way.
