Description

一种阻燃隔热型通信电缆
技术领域
本发明涉及电缆领域，尤其涉及一种阻燃隔热型通信电缆。
背景技术
目前，电线电缆已经广泛被应用于工业生产、交通运输、建筑工程和设施，甚至包括太空和海洋的高端领域，都会使用到电缆，随着社会经济的发展，电缆品种不断更新和完善，生产量也在持续增加，正因电缆在不同领域的应用，人们对其要求也随之而提高，现有的电缆因材质或结构上的问题并不能满足行业的需要，在一些高温的环境下普通的电缆并不能够正常工作，很容易出现电缆内部结构因高温出现工作不稳定的情况，使信号传输失真等缺点。
发明内容
为了克服上述现有技术的缺陷，本发明的目的是提供一种阻燃隔热型通信电缆。
本发明是采取以下技术方案来实现的：一种阻燃隔热型通信电缆，它包括电缆本体，所述电缆本体包括导体、加强层、绝缘层和外护套，所述电缆本体内部设置有多个加强层；所述加强层内部设置有多根导体；所述加强层和导体共同构成缆芯；所述电缆本体内部设置有多根缆芯；且所述缆芯外设置一层绝缘层；所述绝缘层外挤包一层耐高温层；所述耐高温层外挤包一层金属编织层；所述金属编织层外挤包一层外护套。
上述的一种阻燃隔热型通信电缆，所述绝缘层和缆芯之间间隙部分填充有多根金属加强芯。
上述的一种阻燃隔热型通信电缆，所述金属编织层内部环绕设置有多根包塑金属软管。
上述的一种阻燃隔热型通信电缆，所述绝缘层采用交联聚乙烯材料制成。
上述的一种阻燃隔热型通信电缆，所述外护套采用丁腈聚氯乙烯材料制成。
综上所述本发明具有以下有益效果：本发明具有结构设计合理、隔热效果好和使用方便等优点，所述外护套采用丁腈聚氯乙烯材料制成，能够保证电缆本体在油浸或酸碱环境下使用，防止电缆本体出现表面开裂的情况，有效的杜绝电缆出现短路造成电器损坏的不良情况，且延长了电缆的使用寿命。
