High-strength cold-resistant cable and manufacturing process thereof

Abstract

The invention relates to the technical field of wires and cables, and discloses a high-strength cold-resistant cable and a manufacturing process thereof. The high-strength cold-resistant cable comprises a cable core and a fixed protective sleeve, a shielding protective layer is arranged on the outer wall of the cable core, a waterproof protective sleeve is arranged on the outer wall of the shielding protective layer, through mounting grooves are formed in the surface of the fixed protective sleeve, and the mounting grooves are located in the circle center and the surface periphery of the fixed protective sleeve. According to the invention, the fixed protective sleeve can facilitate the installation of a cable core, and the aerogel felt filling layer is arranged in the fixed protective sleeve, so that the strength and cold resistance of the cable are effectively improved; the shielding protection layer and the waterproof protection sleeve can effectively shield external interference signals and enhance the waterproof performance of the whole cable, and the insulating fireproof layer can effectively avoid the situation that fire disasters are caused by cable overload or cable combustion is caused by external open fire.

Description

technical field [0001] The invention belongs to the technical field of wires and cables, and in particular relates to a high-strength cold-resistant cable and a manufacturing process thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. Cables have the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, and aluminum alloy cables. etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] With the progress of modern society, people's life and activities are...

AI Technical Summary

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a high-strength cold-resistant cable and its manufacturing process, which effectively solves the problem that people's life and activity fields gradually expand with the progress of modern society. The application of cables in the field has also become a necessary means for people to survive. When installing cables in some alpine areas, the cables must have certain strength and cold resistance, otherwise the cables may be unstable when used in alpine areas, which leads to people living in alpine areas. Affected, the existing cold resistance is not strong, and it is more troublesome to manufacture, which makes the whole production efficiency lower
