The invention discloses an insulating flame-retardant cable for a new energy automobile and a production process, and relates to the technical field of cables. Comprising a cable body, an inner supporting structure is arranged in the cable body, a core guide groove is formed in the surface of the inner supporting structure, a cable core is arranged on the inner wall of the core guide groove, the surface of the inner supporting structure is wrapped with an insulating layer, an inner protection layer is arranged between the inner supporting structure and the insulating layer, and a first flame-retardant layer is arranged on the surface of the inner protection layer. A second flame-retardant layer is arranged on the side surface of the first flame-retardant layer, and an outer protection layer is arranged on the side surface of the second flame-retardant layer. The added components are effectively improved, and the catalyst, the curing agent and the flame retardant are added in the preparation process, so that the flame retardance of the cable is improved, the cable is prevented from being damaged when the cable is used at a high temperature, the service life of the cable is prolonged, the processing property is good, no toxic gas is released during combustion, and the cable has excellent safety and environmental protection property; the process is simple, the production efficiency is high, and the processing cost can be greatly reduced.

    本发明公开了一种绝缘阻燃型的新能源汽车用电缆及生产工艺,涉及电缆技术领域。包括电缆本体,电缆本体内部设置有内支撑结构,内支撑结构的表面开设有导芯槽,导芯槽的内壁设置有电缆线芯,内支撑结构的表面包裹设置有绝缘层,内支撑结构和绝缘层的之间设置有内保护层,内保护层的表面设置有第一阻燃层,第一阻燃层的侧表面设置有第二阻燃层,第二阻燃层的侧表面设置有外保护层。本发明有效改进了添加成份,在制备的过程中加入催化剂、固化剂和阻燃剂,提高了电缆的阻燃性,避免电缆在高温下使用时,造成电缆损坏,提高了电缆的使用寿命,良好的工艺性能,燃烧时无有毒气体释放,具有优异的安全性和环保性,工艺简单、生产效率高,可大幅度降低加工成本。
