Super-soft light wire cable with rated voltage of 250V and preparation technology thereof

Abstract

The invention relates to a super-soft light wire cable with rated voltage of 250V and a preparation technology thereof. The wire cable is characterized in that a conductor of twisting multi-strand super-thin silver plating brass wires is adopted; the diameter of a single wire of the multi-strand super-thin silver plating brass wires is 0.051mm; a fluorinated ethylene propylene insulating layer is extruded by the thin wall of a high-temperature plastic extruding machine on the periphery of the conductor; the thickness of the insulating layer is 0.16mm; and a fluorinated ethylene propylene sheath layer is arranged on the periphery of the insulating layer. The technology of the sheath layer comprises the steps of: using a concentric twisting conductor of a wire cable bundle twisting machine for the multi-strand super-thin silver plating brass wires; extruding the fluorinated ethylene propylene insulating layer by adopting the thin wall of the high-temperature plastic extruding machine, wherein the insulating layer is subject to single-layer insulation and insulating wire cores are twisted together by using a cable stranding machine; and extruding the fluorinated ethylene propylene sheath layer by adopting the thin wall of the high-temperature plastic extruding machine. The wire cable has the advantages of softness, high-temperature resistant property, anti-aging property, impact resistant property, cracking resistant property and softness under a low-temperature condition, and is suitable for special environments of aerospace, electronic chariots and the like for controlling signal transmission.

Description

Technical field: [0001] The invention relates to a super-flexible light wire and cable with a rated voltage of 250V and its preparation process. Provides high reliability services, and can adapt to signal transmission in narrow spaces and harsh environments such as aerospace and electronic warfare vehicles. Background technique: [0002] At present, there is no ultra-flexible and lightweight data bus cable with a rated voltage of 250V in China. This cable is based on GJB / 773A-2000 "Fluoropolymer Insulated Wire and Cable for Aerospace" and also refers to the US military standard MIL-W-22759 "MILITARY Designed on the basis of the SPECIFICATION SHEET standard. Ordinary data bus cables are made of room temperature materials with poor flexibility, high temperature resistance, and poor aging resistance; and the materials are extruded thick, the outer diameter of the product is large, and the weight is heavy, requiring a large laying space.
