Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a high-strength special conductor. Background Technology

[0002] Conventional cables use steel wire reinforcement to improve their tensile strength, or modify the insulation and sheath materials to enhance their flexibility and tensile strength. To meet special requirements such as high strength and flexibility, and for applications in aerospace and medical devices, high-strength special cables not only employ special insulation and sheath materials, but also modify the conductor structure to ensure sufficient cross-sectional area for current transmission while simultaneously improving tensile strength, maximizing the advantages of both conductor materials and structure.

[0003] When high-strength conductors in existing technologies are used in high-strength applications, the problem of conductor core breakage occurs due to imperfections in materials and structure. It is difficult to meet the electrical and mechanical performance requirements of special environments such as aerospace, and the high tensile strength of the conductor is also difficult to meet. Therefore, we propose a high-strength special conductor. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength special conductor that solves the technical problem of conductor core breakage in high-strength applications caused by imperfections in structure and materials, and meets the electrical and mechanical performance requirements of special environments such as aerospace.

[0006] A high-strength special conductor includes a main body comprising PBO fiber filaments, with tin-plated soft copper strands twisted around the outer periphery of the PBO fiber filaments, and tin-plated copper wires braided around the outer periphery of the tin-plated soft copper strands.

[0007] As a further embodiment of this utility model, a shielding copper strip is wound around the outer perimeter of the tin-plated copper wire, and an insulating sleeve is wound around the outer perimeter of the shielding copper strip.

[0008] As a further embodiment of this utility model, the insulating sleeve one is surrounded by a filler, and the filler completely fills the insulating sleeve two.

[0009] As a further embodiment of this utility model, the insulating sleeve contains multiple sets of main bodies.

[0010] As a further embodiment of this utility model, a tensile structure is added between the inner part of the insulating sleeve II and the main body. The tensile structure includes PBO fiber filaments and an insulating sleeve III, with the insulating sleeve III covering the outside of the PBO fiber filaments.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model employs a special conductor structure composed of multiple sets of main bodies and multiple sets of tensile structures, making the conductor structure more rounded and stable.

[0013] In this invention, high-strength PBO fiber filaments are added during the stranding of the main body. PBO fiber filaments have the tensile strength of 5.8 GPa and the breaking strength of 7.5 kg of international high-end products. The breaking load is more than 11 times that of traditional nickel-plated copper wire. The wear cycle is 5000 times. It also has EMI electromagnetic performance equivalent to metal.
