Embodiment Construction

[0024] With reference to accompanying drawing, the present invention is realized like this: a kind of electric wire for aerospace, it comprises insulation layer 3 and is arranged on the conductor 2 in insulation layer 3, and described conductor 2 is arranged in sequence from inside to outside inner layer 21, The middle layer 22 and the outer layer 23 are twisted concentrically.

[0025] Such as figure 1 As shown, the present invention is an aerospace cable, which includes a shielding layer 1 and several wires arranged in the shielding layer 1; the shielding layer 1 is made of silver-plated or tinned copper-clad aluminum alloy with a thickness of 0.05-0.15mm It is made of braided flat wires, and the braiding density is not less than 85%. The number of wires in the shielding layer 1 can be set to 1-10 according to the needs of users; this structure greatly reduces the specific gravity of the shielding layer 1, so that the shielding layer 1 can The overall weight of layer 1 is r...

Abstract

The invention relates to a wire and cable for aerospace. The wire and cable comprises a shielding layer and a plurality of electric wires arranged in the shielding layer, wherein each electric wire comprises an insulation layer and a conductor arranged in the insulation layer, and the conductor is formed by sequentially concentrically stranding an inner layer, a middle layer and an outer layer from inside to outside. By utilizing the double-layer stranded conductor structure and an innovative material with light specific gravity, the problems of the existing wire and cable that the outer diameter is large and the weight is large can be overcome; and moreover, the wire and cable is scientific and reasonable in overall structure, simple to install, good in shielding effect, convenient to process, remarkable in economic benefit and social benefit, wide in market prospect and convenient to popularize to use; and the wire and cable is suitable for being matched with an aerospace device to use.

Description

technical field [0001] The invention relates to an aerospace wire and cable. Background technique [0002] At present, with the continuous development of the country's aerospace industry, the miniaturization and weight reduction of aircraft have become the bottleneck for improved design; and the wires and cables used for internal wiring of aircraft are not only required to have the characteristics of extremely small size and light weight, but also It must have excellent radiation resistance, high and low temperature resistance, aging resistance, various aviation oil resistance, flame retardant properties, and be easy to weld and process; however, general aerospace wires cannot fully meet the above requirements. The main defects are : ① Stranded structure of the conductor, the material of each strand is made of the same copper material, so that the specific gravity of the conductor is increased, and the product weight has no advantage; ② For 600V products, the thickness of th...
