Description

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or several groups of wires.

[0003] For example, the authorization announcement number CN105741945A is a paper insulated cable with an operating temperature of 90°C. The insulation of the above-mentioned cable has the advantages of high electrical strength, long service life and good thermal stability due to the non-fluidity of the insulating oil; when the cable operating temperature reaches a high temperature of 90°C, the insulating oil continues to maintain a high-viscosity paste without dripping or flowing, and the cable's withstand voltage level always reaches the original optimal level. The design structure can meet the voltage level of paper insulated cables up to 46kV. However, during the use of the wires and cables in the above-mentioned documents, due to the poor elasticity of the outer side of the wires and cables, the wires and cables are easily squeezed by external objects during use, which can easily cause deformation of the wire core inside the wires and cables, and over time, it is easy to cause damage and breakage of the cables;

[0004] At the same time, during the use of the wires and cables in the above-mentioned documents, due to the lack of anti-corrosion structure on the outside of the wires and cables, the wires and cables are corroded by rain for a long time during use in the external environment, which can easily cause aging of the wires and cables, resulting in exposed wire cores and increasing the power transmission risk of the wires and cables. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wire and cable with an anti-corrosion structure is designed, comprising a wire and cable base layer and a steel belt, wherein the outer wall of the wire and cable base layer is bonded to the steel belt, a buffer component is arranged on the outer side of the steel belt, the buffer component comprises a support block, the inner ends of the support blocks on the inner side are bonded to the steel belt, the outer ends of the support blocks on the inner side are bonded to the buffer belt, and the outer walls of the buffer belt are bonded to the support blocks on the outer side.

[0008] Preferably, the outer ends of the outer support blocks are fixedly connected to the connecting parts.

[0009] Preferably, a protective structure is provided on the outer side of the connecting portion, and the protective structure includes a reinforcing portion, an inner wall of the reinforcing portion is bonded to the connecting portion, and an outer wall of the reinforcing portion is bonded to the anti-corrosion portion.

[0010] Preferably, the inner side of the wire and cable base layer is filled with filler.

[0011] Preferably, a plurality of wire cores are arranged inside the filler.

[0012] The utility model proposes an electric wire and cable with an anti-corrosion structure, which has the following beneficial effects: the material of the buffer belt is a silicone material, a cavity is processed inside, and nitrogen is filled inside; the material of the buffer block is butadiene rubber, which has excellent elasticity; when the electric wire and cable are subjected to external pressure, the support block squeezes the buffer belt, and the buffer belt is squeezed so that the internal gas pressure increases, and the external force is buffered by the atmospheric pressure principle, so as to avoid the electric wire and cable being squeezed by external objects and causing damage;

[0013] The material of the reinforcement part is chlorosulfonated polyethylene rubber, which has excellent corrosion resistance and corrosion resistance. The material of the anti-corrosion part is ethylene propylene rubber, which has good heat resistance and cold resistance, as well as excellent corrosion resistance. It protects the wires and cables when rainwater comes into contact with them, improves the corrosion resistance of the wires and cables, and prevents the wires and cables from being corroded by rainwater, resulting in the exposure of the wire core and affecting the power transmission safety of the wires and cables.

[0020] Embodiment 1:

[0021] See attached Figure 1-4 In the present embodiment, a wire and cable with an anti-corrosion structure includes a wire and cable base layer 1 and a steel belt 2. The outer wall of the wire and cable base layer 1 is bonded to the steel belt 2. A buffer component 3 is arranged on the outer side of the steel belt 2. The buffer component 3 includes a support block 302. The material of the buffer belt 301 is a silicone material. A cavity is processed inside and filled with nitrogen. The material of the buffer block 302 is butadiene rubber and has excellent elastic properties. When the wire and cable are subjected to external pressure, the support block 302 squeezes the buffer belt 301. The compression of the buffer belt 301 increases the internal gas pressure, and the external force is buffered by the principle of atmospheric pressure. The inner ends of the inner support blocks 302 are bonded to the steel belt 2, the outer ends of the inner support blocks 302 are bonded to the buffer belt 301, the outer walls of the buffer belt 301 are bonded to the outer support blocks 302, and the outer ends of the outer support blocks 302 are fixedly connected to the connecting parts 7. The material of the connecting parts 7 is an organic silicone material with excellent bonding properties, thereby improving the connection strength between the support blocks 302 and the protective structure.

[0022] A protective structure 4 is arranged on the outside of the connecting part 7. The material of the reinforcing part 4a1 is chlorosulfonated polyethylene rubber, which has excellent corrosion resistance and corrosion resistance. The material of the anti-corrosion part 4a2 is ethylene propylene rubber, which has good heat resistance and cold resistance, as well as excellent corrosion resistance. The protective structure 4 includes a reinforcing part 4a1, the inner wall of the reinforcing part 4a1 is bonded to the connecting part 7, and the outer wall of the reinforcing part 4a1 is bonded to the anti-corrosion part 4a2. The inner side of the wire and cable base layer 1 is filled with a filler 6, and the material of the filler 6 is alkali-free glass fiber rope to improve the strength of the wire and cable. A plurality of wire cores 5 are arranged inside the filler 6.

[0023] Working principle:

[0024] The material of the buffer belt 301 is silicone material, with a cavity processed inside and filled with nitrogen. The material of the buffer block 302 is butadiene rubber, which has excellent elastic properties. When the wires and cables are subjected to external pressure, the support block 302 squeezes the buffer belt 301, and the buffer belt 301 is squeezed so that the internal gas pressure increases. The external force is buffered by the atmospheric pressure principle, so as to avoid the wires and cables being squeezed by external objects and causing damage;

[0025] The material of the reinforcement part 4a1 is chlorosulfonated polyethylene rubber, which has excellent corrosion resistance and corrosion resistance. The material of the anti-corrosion part 4a2 is ethylene propylene rubber, which has good heat resistance and cold resistance, as well as excellent corrosion resistance. When rainwater comes into contact with the wires and cables, the wires and cables are protected, the corrosion resistance of the wires and cables is improved, and the wires and cables are prevented from being corroded by rainwater, resulting in the core being exposed and affecting the power transmission safety of the wires and cables.

[0026] Embodiment 2:
