Abstract

Technical Field

[0002] A high-strength copper core wire and cable is a cable that uses high-strength copper wire as a conductor for transmitting electricity and signals. Copper has been widely used in the manufacture of wire and cable for a long time due to its excellent electrical conductivity, thermal conductivity, and good corrosion resistance. With the development of technology and the improvement of industrial automation, the performance requirements for wire and cable are also constantly increasing, and high-strength copper core wire and cable came into being. Wire and cable are wire products used to transmit electromagnetic energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wire and cable are also simply called cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as an aggregate composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, general protective layer, and outer protective layer. And there are still some defects when using the cable. Compared with ordinary copper core wire and cable, the conductor of high-strength copper core wire and cable is made of special materials and processes, has a higher tensile strength, and can withstand large tensile forces without breaking, which is particularly important for environments that need to withstand mechanical stress. The conductor of high-strength copper core wire and cable usually uses high-purity copper materials to ensure excellent electrical conductivity even in a smaller diameter, reduce resistance, and reduce energy loss. In some environments, wire and cable may be corroded. High-strength copper core wire and cable usually use plating or alloy technology to improve its corrosion resistance and extend its service life.
[0003] When using cables during construction, the cables are often in outdoor places where they are prone to moisture, wind, sun exposure, and are easily trampled on, resulting in aging of the cable surface, especially at the bending positions of the cable, which then easily leads to damage to the cable and safety hazards such as cable leakage. Content of the Utility Model

[0005] To achieve the above object, the present utility model provides the following technical solution: a high-strength copper core wire and cable, including a copper core conductor, a plurality of the copper core conductors are symmetrically arranged, an inner insulation sheath is arranged outside the copper core conductor, an inner fireproof layer is fixedly connected to the outside of the inner insulation sheath, an inner waterproof layer is fixedly connected to the outside of the inner fireproof layer, a first clamping layer is fixedly connected to the outside of the inner waterproof layer, an elastic filler is fixedly connected to the outside of the first clamping layer, and a second clamping layer is fixedly connected to the outside of the elastic filler.

[0013] Compared with the prior art, the present utility model provides a high-strength copper core wire and cable, having the following beneficial effects:
[0014] 1. By setting the elastic filler and structures such as the first clamping layer and the second clamping layer, when the cable is externally squeezed and trampled, through the contraction of the elastic filler, the external force directly acting on the copper core conductor can be relieved.

Through the arrangement of structures such as the first clamping layer 6 and the second clamping layer 8, when the cable is externally squeezed and trampled, through the contraction of the elastic filler 7, the external force directly acting on the copper core conductor 1 can be relieved. When the external force disappears, through the elasticity of the elastic filler 7 itself, it returns to its original state, making the depressed part due to force return to flat. During this process, the copper core conductor 1 is wrapped by the elastic filler 7 and is less stressed, avoiding damage and breakage to the greatest extent.
