Description

防火电缆
技术领域
本实用新型涉及一种防火电缆。
背景技术
002284235号实用新型专利给出了一种防火电缆。它在铜管内设有多跟铜导线,并在铜导线间填充氧化镁,起到防火作用,但其外部采用时铜管,直接裸漏在外,温度稍高就会是的铜管温度上升,虽然铜导线间有氧化镁,但热辐射依然会造成内部的铜导线被加热,影响电缆的使用寿命。 实用新型内容
本实用新型的目的就是为解决上述问题,提供一种结构简单,使用方便,可有效提高电缆耐高温性能的防火电缆。
为实现上述目的,本实用新型采用如下技术方案:
一种防火电缆,它包括铜管,在铜管内设有若干个铜导线,铜导线间填充耐火材料,所述铜管外部设有石棉防护层。
本实用新型在铜管外部包裹了石棉防护层,从而有效减少了外部高温对铜管的影响,并进而减少铜管对管内铜导线的热辐射。
本实用新型的有益效果是:结构简单,使用方便,耐高温能力强。
附图说明
图1为本实用新型的结构示意图。
其中,1铜管,2铜导线,3耐火材料,4石棉防护层。
具体实施方式
下面结合附图与实施例对本实用新型做进一步说明。
图1中,它包括铜管1,在铜管1内设有若干个铜导线2,铜导线2间填充耐火材料3,所述铜管1外部设有石棉防护层4。
