Abstract

本实用新型公开了一种耐火阻燃电缆,包括导体和导体外包的绝缘层,在导体和绝缘层之间包裹有云母粉和弹性陶瓷超细粉制成的耐火阻燃层。本实用新型从表面上看与一般的普通电缆没有区别,但电缆的内部结构有革命性的改变,具有安全、耐火阻燃的特性,本实用新型不仅能在线路过载的情况下安全供电,而且在发生火灾的现场也不会产生助燃作用,并能正常供电,有利于火灾救护和灭火。

Description

一种耐火阻燃电缆
技术领域
本实用新型涉及电线、电缆领域,具体是一种耐火阻燃电缆。 
背景技术
在公知技术中,现有的普通双股电缆的结构是在两根导电体如铜线或铝线外包覆一层聚氯乙烯绝缘材料或橡胶绝缘护套构成。上述结构的电线电缆其外包的绝缘材料不耐热、耐火。但导体过载时会引起外包的材料燃烧,造成相间短路,引发火灾。 
发明内容
本实用新型的目的是提供一种生产成本低,加工工艺简单的耐火阻燃电缆,其能在电荷过载的情况下,导体不起火,保证正常供电。 
本实用新型解决上述技术问题采用的技术方案是:一种耐火阻燃电缆,包括导体和导体外包的绝缘层,在导体和绝缘层之间设置有耐火阻燃层。 
本实用新型从表面上看与一般的普通电缆没有区别,但电缆的内部结构有革命性的改变,具有安全、耐火阻燃的特性,本实用新型不仅能在线路过载的情况下安全供电,而且在发生火灾的现场也不会产生助燃作用,并能正常供电,有利于火灾救护和灭火。 
附图说明
图1是本实用新型的结构示意图。 
具体实施方式
    下面结合附图对本实用新型作进一步的说明。如图1所示,本实用新型包括导体1和导体外包的绝缘层3,在导体和绝缘层之间设置有2,该耐火阻燃层由云母粉和弹性陶瓷超细粉喷覆在导体上制成。
