Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically a high-temperature resistant composite cable. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for control installation, connecting equipment, and transmitting power.

[0003] A composite high-temperature resistant cable, disclosed in publication number CN222319821U, includes several conductor bundles, a stabilizing layer disposed outside the conductor bundles, and a protective sleeve disposed outside the stabilizing layer. A heat-resistant layer is further disposed between the protective sleeve and the stabilizing layer. This heat-resistant layer comprises an outer layer connected to the inner wall of the protective sleeve, an inner layer wrapped around the outside of the stabilizing layer, and a middle layer disposed between the outer and inner layers. The outer layer is a polyphenylene ether layer, the middle layer is a glass fiber layer, the inner layer is a silicone rubber layer, the protective sleeve is a polyvinyl chloride layer, and the stabilizing layer is a galvanized steel strip braided layer. By incorporating a heat-resistant layer composed of the outer, middle, and inner layers, the cable's high-temperature resistance is enhanced layer by layer. External heat is less likely to transfer to the conductor bundles, effectively reducing the impact of high temperatures on the conductor bundles. This cable exhibits excellent high-temperature resistance.

[0004] While existing technologies have improved the high-temperature resistance of cables to some extent, their buffering and compressive strength is poor. Therefore, we propose a high-temperature resistant composite cable. Utility Model Content
