An insulating layer 2, with a spiral stripe logo 3 printed on the outside of the insulating layer 2;

[0032] Its preparation process is as follows:

[0033] 1) Conductor stranding: use annealed silver-plated (nickel) copper conductors for stranding with a pitch ratio of less than 20;

[0034] 2) Insulation layer extrusion: inner and outer insulation layers are co-extruded (extrusion temperature is 245-315°C) to form a double-layer insulation layer. The rubber material of the insulation layer is X-ETFE, and the concentricity of the insulation layer is 75%. The thinnest point of the layer is 0.08mm, and the thinnest point of the outer insulating laye...

Abstract

The invention discloses a spiral strip identification high-temperature resistance flexible electric wire and cable for aviation. With regard to a high-temperature resistance flexible electric wire which is directly formed by a single insulating core wire, spiral strip identification is printed on an insulating layer; with regard to a high-temperature resistance flexible electric cable consisting of a single insulating core wire, a shielding layer and a jacket layer, spiral strip identification is printed on the jacket layer; with regard to a high-temperature resistance flexible electric cable consisting of a plurality of insulating core wires, a shielding layer and a jacket layer, spiral strip identification is printed on an insulating layer and / or the jacket layer; with regard to a high-temperature resistance flexible electric cable consisting of a plurality of insulating core wires and a jacket layer, spiral strip identification is printed on an insulating layer and / or the jacket layer; and each insulating core wire consists of a conductor and an insulating layer coating the conductor; each conductor is manufactured by twisting conductor single wires; and the minimum diameter of each conductor single wire is 0.051 mm. The electric wire and cable provided by the invention are easy to distinguish and identify, and have good high-temperature and low-temperature resistance, and radiation resistance, and are softer and easy to lay and mount.

Description

technical field [0001] The invention relates to a high-temperature-resistant flexible wire and cable with spiral stripe marking for aerospace and a preparation process thereof. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of my country's wire and cable industry, the number of new enterprises is increasing, the product categories are becoming more and more diversified, and the classification and recycling of products will become more complicated. [0003] In recent years, the wire and cable industry has more clearly defined the "green" product standards. Product standards such as halogen-free, low-smoke, flame-retardant, and lead-free have becom...
