Description

防火电缆
技术领域
本实用新型涉及一种通信电缆,具体的说是一种防火电缆。
背景技术 
电缆在日常生活中应用广泛,作为数据的输送介质,作用具大。
在实际电缆应用中,常常会遇到火灾等情况,如电缆防火性较差,线缆易被烧断,使数据传输中断。同时,如果线缆在燃烧过程中产生大量的有毒气体和烟尘,那么会对人员的逃生产生极大的影响,甚至成为安全的隐患。
实用新型内容
本实用新型的目的在于提供一种防火性能好的防火电缆。
本实用新型所采用的技术方案是:一种防火电缆,包括线芯、内绝缘层、阻燃泡沫层、金属防护层、耐火防护层、外护套,内绝缘层内设有至少一个线芯;所述内绝缘层外设有阻燃泡沫层;所述阻燃泡沫层呈微泡蜂窝结构,其外设有金属防护层;所述金属防护层由金属细丝线编织而成;金属防护层外设有一种耐火防护层;所述耐火防护层外设有外护套。
本实用新型结构简单,其电缆防火性好,在遇明火时,其多层防火设计可有效的增强电缆防火性,保护电缆使用安全。
附图说明
附图1是本实用新型的结构示意图,也是摘要用图。
具体实施方式
现结合附图及实施例对本实用新型作出进一步的说明。
实施例:
一种防火电缆,包括线芯1、内绝缘层2、阻燃泡沫层3、金属防护层4、耐火防护层5、外护套6,内绝缘层2内设有至少一个线芯1;所述内绝缘层2外设有阻燃泡沫层3;所述阻燃泡沫层3呈微泡蜂窝结构,其外设有金属防护层4;所述金属防护层4由金属细丝线编织而成;金属防护层4外设有一种耐火防护层5;所述耐火防护层5外设有外护套6。
