Embodiment approach
[0030] As an embodiment of the present invention, a storage layer 4 is installed in the main body 1; the storage layer 4 is closely attached to the inner wall of the main body 1; the storage layer 4 is a thin-walled hollow structure made of water-soluble materials; The storage layer 4 is filled with a polyurethane plugging agent; the polyurethane plugging agent is a common commercially available product;
[0031] When working, when the cable is in use, after a small gap appears on the main body 1 due to external force, when the external water vapor penetrates into the main body 1, the water vapor comes into contact with the storage layer 4, and under the action of water vapor, the outer wall of the storage layer 4 appears. Dissolution, because the water vapor diffuses in the main body 1 following the principle of near first and then far, so the storage layer 4 close to the gap is the first to dissolve and rupture, so that the polyurethane plugging agent in the storage layer 4 f...

The invention belongs to the technical field of cables, and particularly relates to a corrosion-resistant cable, which comprises a main body, and is characterized in that a through hole is formed in the main body; the main body is made of polyethylene plastic; 30%-35% of sericite powder and 5%-10% of iron oxide powder are added into the polyethylene plastic; a reinforcing layer is mounted in the main body; the reinforcing layer is clung to the inner wall of the main body; an isolation bracket is mounted in the main body; the tail end of the isolation bracket extends into the inner wall of themain body; the space of the isolation bracket in the main body is divided into a plurality of subspaces; the reinforcing layer is positioned between the main body and the tail end of the isolation bracket; a wire core is arranged in the main body; the wire core is located in a subspace formed between the main body and the isolation bracket; the residual space in the main body is filled with a filler; the cable disclosed by the invention has good corrosion resistance in various environments, and meanwhile, has certain self-repairing capability after being slightly damaged.
Description
technical field [0001] The invention belongs to the technical field of cables, in particular to a corrosion-resistant cable. Background technique [0002] A cable is an electrical energy or signal transmission device, usually twisted by several or several groups of wires, each group of wires is insulated from each other, and often twisted around a center, the entire outer surface is covered with a high degree of insulation Layer, the cable has the characteristics of internal energization and external insulation. With the rapid development, the demand and requirements for wire and cable are constantly improving. According to the geographical location and purpose of the cable application, the cable is installed in different ways. At the same time , Different laying methods have requirements for the mechanical properties and corrosion resistance of the cable, especially in some places with high environmental corrosion, the outer layer of the cable is easily corroded, destroying...
