Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and in particular to a wire and cable with a long service life. Background Technology

[0002] Existing wires and cables, due to environmental corrosion and the thermal effect of current, gradually degrade in performance over long-term use, making it difficult to operate stably throughout the entire lifespan of a building. This necessitates mid-life replacement, increasing maintenance costs and electrical safety hazards. Furthermore, during prolonged overload operation, the insulation material of wires and cables is prone to melting due to excessively high temperatures, leading to insulation failure, short circuits, and potentially fires. Therefore, a long-life wire and cable has been designed to address these issues. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a long-service-life wire and cable. The inner insulation layer ensures electrical isolation between the conductor and the outside environment; the reinforcing layer enhances the cable's mechanical strength and prevents damage from external forces; the waterproof layer effectively prevents moisture intrusion, avoiding electrical performance degradation due to dampness; the outer insulation layer further enhances the electrical isolation effect; and the protective sheath provides additional physical and chemical protection, thereby extending the stable operating time of the wire and cable throughout the building's entire life cycle, reducing maintenance costs and potential electrical hazards.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A long-service-life wire and cable includes: a conductor; an inner insulation layer wrapped around the outer surface of the conductor; a reinforcing layer wrapped around the outer surface of the inner insulation layer; a waterproof layer wrapped around the outer surface of all the reinforcing layers; an outer insulation layer wrapped around the outer surface of the waterproof layer; and a protective sheath wrapped around the outer surface of the outer insulation layer.

[0006] By adopting the above scheme, this multi-layered wire and cable design provides comprehensive protection. The inner insulation layer ensures electrical isolation between the conductor and the outside environment, the reinforcing layer enhances the mechanical strength of the cable and prevents damage from external forces, the waterproof layer effectively prevents moisture intrusion and avoids degradation of electrical performance due to moisture, the outer insulation layer further enhances the electrical isolation effect, and the protective sheath provides additional physical and chemical protection, thereby extending the stable operating time of the wire and cable throughout the entire life cycle of the building, reducing maintenance costs and electrical hazards.

[0007] Furthermore, the inner insulation layer is made of cross-linked polyolefin material.

[0008] By adopting the above scheme, cross-linked polyolefin materials have excellent electrical properties, mechanical properties and heat resistance, can effectively resist the thermal effect of electric current and environmental erosion, maintain long-term stable insulation performance, and thus extend the service life of wires and cables.

[0009] Furthermore, the reinforcing layer is woven from aramid yarn.

[0010] By adopting the above scheme, aramid yarn has excellent properties such as high strength, high modulus, low density, high temperature resistance, and chemical corrosion resistance. The reinforcing layer woven with aramid yarn can significantly enhance the mechanical strength and tensile strength of wires and cables, effectively prevent cable damage caused by external forces, and further extend the service life.

[0011] Furthermore, the outer insulating layer is made of nylon material.

[0012] By adopting the above scheme, nylon material has good electrical insulation properties, mechanical strength and wear resistance. The outer insulation layer made of nylon material can further enhance the electrical isolation effect and physical protection capability of wires and cables, and improve the overall durability and safety of wires and cables.

[0013] Furthermore, flame-retardant PP filler rope is used to fill the space between the waterproof layer and the reinforcing layer.

[0014] By adopting the above solution, the flame-retardant PP filler rope not only has good flame-retardant properties and can slow down the spread of fire when a fire occurs, but it can also fill the gap between the waterproof layer and the reinforcing layer, enhance the overall structural stability of the cable, prevent mechanical damage or moisture intrusion caused by the gap, and thus extend the service life of the wire and cable.

[0015] Furthermore, the waterproof layer is made of a waterproof film.

[0016] By adopting the above solution, the waterproof film has excellent waterproof performance, which can effectively prevent moisture from penetrating into the inside of the wire and cable, protect the core and insulation layer from moisture, thereby maintaining the electrical and mechanical properties of the wire and cable and extending its service life.

[0017] Furthermore, the protective skin is made of Teflon coating.

[0018] By adopting the above-mentioned solution, Teflon coatings possess excellent properties such as high temperature resistance, chemical corrosion resistance, non-stickiness, and low coefficient of friction. Protective sheaths made with Teflon coatings can provide additional physical and chemical protection for wires and cables, preventing cable damage caused by high temperature, chemical corrosion, or mechanical friction, and further extending the service life of wires and cables.
