Embodiment Construction

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific embodiments, structural features and effects of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] Such as figure 1 The tensile and fire-resistant cable shown includes an inner conductor 1, a shielding layer 2 coated by the conductor 1, and an insulating layer 3 coated by the shielding layer 2. The material of the insulating layer 3 is modified cross-linked ethylene-tetrafluoroethylene Copolymer material, the thinnest thickness of the insulating layer 3 is not less than 0.105mm. The conductor 1 is formed by twisting carbon fiber monofilaments and graphene nanomaterial nanotube monofilaments; the monofilaments are twisted into a two-layer structure or a multilayer structure. The central axis of the monofilament of the same layer forms a circle, which is conc...

Abstract

The invention belongs to the technical field wires and cables, and specifically relates to a tensile fire resistant cable. The tensile fire resistant cable comprises an internal conductor, a shieldinglayer coated outside the conductor and an insulating layer coated outside the shielding layer, wherein the conductor is stranded by carbon fiber monofilaments and nanotube monofilaments of a graphenenano material; the shielding layer is a graphene-rubber composite layer prepared by compositing graphene and rubber; the insulating layer is externally coated with a fireproof layer; and the fireproof layer is made of a 90-degree high-flame-retardant low-smoke halogen-free polyolefin material. The cable adopts the graphene nano material to serve as a force bearing part or a conductive part of thewire, so that the conductivity and the tensile capacity of the cable can be significantly improved; and the cable adopts the 90-degree high-flame-retardant low-smoke halogen-free polyolefin to serveas the fire-proof layer, so that the overall structure is simpler, thereby being simpler in overall structure, and playing an excellent effect of fire protection and heat insulation.

Description

Technical field [0001] The invention belongs to the technical field of wires and cables, and specifically relates to a tensile and fire-resistant cable. Background technique [0002] Graphene materials have excellent electrical and mechanical properties. The conductivity is about 3 times that of aluminum and 1.85 times that of copper. The material has stable conductivity. At the same time, graphene materials are the thinnest and hardest nanomaterials, with extremely strong tensile strength (about 100 GPa). [0003] The research history of the new nanomaterial graphene is relatively short. Due to its excellent material properties, a lot of research work has been carried out in preparation and application research at home and abroad, and breakthrough research results have been obtained. [0004] In terms of the preparation of graphene materials, Korean scientists have discovered a method to prepare large-size and high-quality graphene films; American researchers have developed new met...
