Description

Technical Field

[0001] The utility model relates to the field of cables, and more specifically to a control cable with good corrosion resistance. Background Art

[0002] Control cables play a vital role in modern industrial and electrical systems. They are widely used in a wide range of fields, including power systems, transportation and energy sectors, industrial automation, chemical and petrochemical companies, and medical equipment. With technological advancements and industrial development, the requirements for control cables are becoming increasingly demanding.

[0003] Existing control cables often lack corrosion resistance in harsh environments, such as those with strong acids, strong bases, or high humidity. This can damage the cable insulation and expose the conductor, compromising the cable's electrical performance and stability. In some exceptional cases, such as when the cable's outer layer is corroded by acidic materials, existing control cables often fail to provide effective emergency protection, leading to data loss or equipment damage. Over long-term use, some control cables can become loose and mechanically unstable due to physical forces such as squeezing and pulling from the external environment, compromising transmission efficiency and reducing their service life.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a control cable, comprising an outer sheath, an outer corrosion-resistant layer, a copper tube, a filling layer and a wrapping layer arranged in sequence from the outside to the inside, the outer sheath having an outer coating, the outer coating adopts corrosion-resistant epoxy resin paint, the outer corrosion-resistant layer adopts polyvinyl chloride resin, the filling layer is filled with lime powder, the wrapping layer has multiple cable cores, the cable core comprises a conductor, an insulating layer and an inner corrosion-resistant layer arranged in sequence from the inside to the outside, the inner corrosion-resistant layer adopts chloroprene rubber, and the outer sheath adopts polyvinyl chloride material.

[0006] Furthermore, there is a gap between the wrapping layer and the copper tube, and the gap forms the filling layer.

[0007] This makes it easier to fill in lime powder.

[0008] Furthermore, the wrapping layer is an aluminum-plastic composite tape wrapping layer.

[0009] Thereby providing a certain shielding performance.

[0010] Furthermore, the insulation layer is a polyethylene insulation layer.

[0011] Thereby improving the insulation performance of the cable.

[0012] Furthermore, the conductor is a copper conductor or an aluminum conductor.

The control cable of the present application has an outer coating, an outer corrosion-resistant layer, and an inner corrosion-resistant layer, so that the cable has good corrosion resistance, thereby being able to protect the conductor in harsh environments and enable it to operate stably for a long time.

[0017] 2. In the control cable of the present application, the copper tube plays a protective role and is convenient for filling with lime powder.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-3The control cable shown has good corrosion resistance, comprising an outer sheath 2, an outer corrosion-resistant layer 3, a copper tube 4, a filling layer 5 and a wrapping layer 6 arranged in sequence from the outside to the inside. The outer sheath 2 has an outer coating 1, the outer coating 1 adopts corrosion-resistant epoxy resin paint, the outer corrosion-resistant layer 3 adopts polyvinyl chloride resin, the filling layer 5 is filled with lime powder, and the wrapping layer 6 has multiple cable cores, the cable core comprises a conductor 9, an insulating layer 8 and an inner corrosion-resistant layer 7 arranged in sequence from the inside to the outside, the inner corrosion-resistant layer 7 adopts chloroprene rubber, and the outer sheath 2 adopts polyvinyl chloride material.

[0025] A gap is defined between the wrapping layer 6 and the copper tube 4, forming the filling layer 5. The wrapping layer 6 is an aluminum-plastic composite tape wrapping layer. The insulation layer 8 is a polyethylene insulation layer. The conductor 9 is a copper or aluminum conductor. The control cable has a circular structure, with multiple cable cores divided into a central cable core and multiple circumferential cable cores. The multiple circumferential cable cores are divided into multiple turns, with the multiple circumferential cable cores within a turn being distributed in a circular pattern with equal spacing.

[0026] Working Principle: The control cable of the present application has an outer coating, an outer corrosion-resistant layer, and an inner corrosion-resistant layer, which makes the cable have good corrosion resistance, thereby protecting the conductor in harsh environments and enabling long-term stable operation. The copper tube plays a protective role and is convenient for filling with lime powder. Even if the outer layer is corroded by acidic materials, the leakage of lime powder can neutralize the acidic substances and reduce the corrosion rate of the acidic substances, leaving sufficient time for the equipment using the cable to save data and protect the equipment. In addition, the cable core is reasonably arranged, compact and stable in structure, which improves the mechanical stability and transmission efficiency of the cable.

[0027] During production, the prepared cable cores are arranged as required to form a central core and multiple circumferential cores. A layer of aluminum-plastic composite tape is then wrapped around the cores to provide shielding and mechanical strength. The gap between the copper tube and the tape is then filled with lime powder, ensuring a tight seal. An outer corrosion-resistant layer is then applied to the copper tube, followed by an outer sheath. Finally, an outer coating is applied to the outer sheath.

[0028] Although the present invention has been illustrated and described with respect to preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
