Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable with good corrosion resistance for electrical automation engineering. Background Technique

[0002] Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single-stranded or multi-stranded wires and insulating layers, and are used to connect circuits, electrical appliances, etc.

[0003] However, in order to avoid being eroded by some corrosive substances, the existing cables usually add a layer of corrosion-resistant protection on the surface. However, during the process of dragging and installing the cables by personnel, the corrosion-resistant protection on the surface is easily scratched due to abrasion, reducing the subsequent corrosion-resistant protection effect and affecting the safe operation and service life of the cables. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cable with good corrosion resistance for electrical automation engineering, which has the advantages of good corrosion-resistant protection effect, improved wear resistance on the surface, and ensuring the long-term safe use and operation of the cable.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cable with good corrosion resistance for electrical automation engineering, including a cable body. Rubber protection rings are sleeved at both ends of the outer surface of the cable body. A nylon fiber mesh is fixedly connected to the surface of the rubber protection rings. Steel wires are fixedly connected to both ends of the rubber protection rings. The cable body includes a core. An intermediate layer is wrapped on the surface of the core. A protective layer is wrapped on the outer surface of the intermediate layer. The protective layer includes a silicone rubber layer and a polyvinyl chloride layer. A corrosion-resistant layer is coated on the outer surface of the protective layer. The corrosion-resistant layer includes a polytetrafluoroethylene coating and a chlorinated rubber coating.

[0006] As a preferred solution, the intermediate layer includes a ceramic fiber rope filling layer, a mica tape winding layer, and a mineral insulation layer. The inner surface of the mica tape winding layer wraps around the outer surface of the mineral insulation layer. The inner surface of the ceramic fiber rope filling layer wraps around the outer surface of the mica tape winding layer.

[0007] As a preferred solution, the inner surface of the silicone rubber layer wraps around the outer surface of the polyvinyl chloride layer. A steel tape armor layer is fixedly connected to the middle end of the polyvinyl chloride layer.

[0008] As a preferred solution, the inner surface of the polytetrafluoroethylene coating is coated on the outer surface of the chlorinated rubber coating. The thickness of the polytetrafluoroethylene coating is equal to the thickness of the chlorinated rubber coating.

[0009] As a preferred solution, a rubber protective sleeve is sleeved on the right end of the cable body, and the thickness of the rubber protective sleeve is two millimeters.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Through the arrangement of the polytetrafluoroethylene coating and the chlorinated rubber coating in the corrosion-resistant layer, a double-layer corrosion-resistant protection is formed on the outer surface of the cable body. At the same time, due to the good wear-resistant performance of the polytetrafluoroethylene coating, the probability of the corrosion-resistant layer being worn is effectively reduced, and the corrosion-resistant performance of the cable body during long-term use is improved. Through the arrangement of the silicone rubber layer and the polyvinyl chloride layer in the protective layer, a double-layer waterproof protection can be formed around the cable body, and at the same time, a good corrosion-resistant protection is further formed around the cable body, greatly improving the corrosion-resistant performance of the cable body. Through the arrangement of the rubber protection ring, the cable body can be effectively supported during the installation or dragging of the cable body, avoiding the corrosion-resistant layer from coming into contact with the ground during the dragging process and causing wear and scratches, ensuring that the corrosion-resistant layer can form protection for the cable body for a long time. Through the arrangement of the nylon fiber mesh and the steel wire, a good strength protection is formed inside the rubber protection ring, effectively avoiding the rubber protection ring from breaking during the dragging force application process and improving the service life of the rubber protection ring.

[0012] 2. Through the arrangement of the ceramic fiber rope filling layer, the mica tape wrapping layer and the mineral insulation layer in the intermediate layer, due to the good insulation performance of the mica tape wrapping layer and the mineral insulation layer, a double-layer insulation protection is formed inside the cable body, effectively improving the insulation performance inside the cable body. At the same time, due to the good fireproof and flame-retardant performance of the ceramic fiber rope filling layer and the mica tape wrapping layer, a double-layer fireproof and flame-retardant protection is formed inside the cable body, effectively improving the fireproof and flame-retardant performance of the cable body. Through the arrangement of the steel tape armor layer, a good compressive and tensile strength protection is formed inside the protective layer, effectively improving the compressive and tensile performance of the cable body. Through the arrangement of the rubber protective sleeve, the end of the cable body can be effectively protected, avoiding the external water body from entering the inside of the cable body through the end during the placement of the cable body, ensuring that the cable body can be used normally subsequently.
