Problems solved by technology

[0002] Cables are usually composed of several wires or groups of wires. When laying cables at high altitudes, the cables are usually suspended in the air. The toughness and tear resistance of the existing cables are not good, which is easy to cause damage to the cables. Damage to the cable will lead to the rupture of the cable and affect the service life of the cable, so we propose a high-toughness tear-resistant cable for high altitude and its production process to solve this problem

Abstract

The invention relates to the technical field of a cable and particularly relates to a high-altitude high-toughness tear-resistant cable. The cable includes a first guide core, wherein the first guidecore is externally wrapped in a first wrapping layer, the first wrapping layer is externally wrapped in a second guide core, the second guide core is externally wrapped in a second wrapping layer, thesecond wrapping layer is externally wrapped in a third guide core, the third guide core is externally wrapped in an insulation layer, the insulation layer is externally fixedly connected with a toughlayer, the tough layer is externally fixedly connected with a tear-resistant layer, the tear-resistant layer is externally fixedly connected with a tensile resistant layer, the tensile resistant layer is externally pasted with a weather resistant layer, and a thickness ratio of the weather resistant layer to the tensile resistant layer is 1:2. The invention further provides a high-altitude high-toughness tear-resistant cable production process. The high-altitude high-toughness tear-resistant cable is advantaged in that cable toughness and tear-resistant capability are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-toughness tear-resistant cable for high altitudes and a production process thereof. Background technique [0002] Cables are usually composed of several wires or groups of wires. When laying cables at high altitudes, the cables are usually suspended in the air. The toughness and tear resistance of the existing cables are not good, which is easy to cause damage to the cables. Damage to the cable will lead to the rupture of the cable and affect the service life of the cable. Therefore, we propose a high-toughness tear-resistant cable for high altitude and its production process to solve this problem. Contents of the invention [0003] The object of the present invention is to solve the shortcomings in the prior art, and propose a high-altitude high-toughness tear-resistant cable and its production process. [0004] In order to achieve the above object, the present inventio...
