Abstract

一种防火引入光缆,包括缆芯及外护层,在缆芯与外护层之间设置不锈钢套管,外护层采用低烟无卤阻燃材料制作,这种光缆具有良好的防火效果,使用场合一旦出现火灾也不易受损。

Description

防火引入光缆
所属技术领域
本实用新型涉及一种具有良好防火性能的光缆。
背景技术
现有引入光缆由于外护层及缆芯内的光纤的紧套管均不能有效地防火,一旦使用场合出现火灾,很容易使缆芯内光纤受损而造成通信中断。
发明内容
为了克服现在引入光缆防火性能差的不足,本实用新型提供一种具有良好防火性能的引入光缆。
本实用新型所提供的防火引入光缆包括缆芯(1)及外护层(2),缆芯(1)内含有光纤(3)及纤膏(4),在缆芯(1)与外护层(2)之间设置不锈钢套管(5)。
本实用新型的外护层可以采用低烟无卤阻燃材料制作。
本实用新型的有益效果是具有良好的防火性能,使用场合一旦出现火灾,本实用新型也不易受损。
附图说明
图1是本实用新型横截面的示意图。
在图中,1、缆芯,2、外护层,3、光纤,4、纤膏,5、不锈钢套管。
具体实施方式
本实用新型在制作缆芯(1)时外包不锈钢套管(5),再在不锈钢套管(5)外包覆低烟无卤阻燃材料外护层(2)。
