Description

一种防冻耐压电缆
技术领域
本发明涉及一种防冻耐压电缆，属于电力电缆技术领域。
背景技术
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，在寒冷地区电缆由于低温造成断裂等各种故障，需要一种抗冻能力强，耐压性能好的电缆。
发明内容
为克服上述不足，本发明目的提供一种防冻耐压电缆。
本发明的方案如下：一种防冻耐压电缆，包括导体、绝缘层、导热层一、加热层、导热层二、屏蔽层和护套，所述导体外挤包绝缘层，所述绝缘层外挤包导热层一，所述导热层一外挤包加热层，所述加热层外挤包导热层二，所述导热层二外挤包屏蔽层，所述屏蔽层外挤包护套，所述导体是由多股无氧铜丝绞合而成，所述绝缘层是由硅胶制成，所述护套内设置有气管，所述气管内设置有惰性气体。
本发明的有益效果：本发明结构简单合理，能够有效的抗冻。
附图说明
图1为发明的结构示意图。
具体实施方式
下面结合附图对发明做进一步说明。
一种防冻耐压电缆，包括导体1、绝缘层2、导热层一3、加热层4、导热层二5、屏蔽层6和护套7，所述导体1外挤包绝缘层2，所述绝缘层2外挤包导热层一3，所述导热层一3外挤包加热层4，所述加热层4外挤包导热层二5，所述导热层二5外挤包屏蔽层6，所述屏蔽层6外挤包护套7，所述导体1是由多股无氧铜丝绞合而成，所述绝缘层2是由硅胶制成，所述导热层一3和导热层二4是由玻璃纤维制成，所述护套内设置有气管8，所述气管8内设置有惰性气体。
尽管上文对本发明的具体实施方式给予了详细描述和说明，但是应该指明的是，我们可以依据本发明的构想对上述实施方式进行各种等效改变和修改，其所产生的功能作用仍未超出说明书及附图所涵盖的精神时，均应在本发明的保护范围之内。
