Description

一种稳定型防火电缆
技术领域
本发明涉及电力传输技术领域，尤其是一种稳定型防火电缆。
背景技术
目前，随着清洁能源的发展，电力资源高速发展，随着核电站、水电站以及风能发电的建设，电缆在生活中成为常用的工具。电缆一般都应用于一些恶劣的工作环境中，有些地方存在着火灾的风险，万一发生火灾对于电缆的损害是相当的严重，目前很多电缆在防火方面只是单纯的加个防火的绝缘套，在耐火性能方面存在着易燃烧，阻燃能力弱，耐腐蚀能力不强，燃烧的时候容易释放大量的有毒气体，对于环境造成了污染。
发明内容
为了克服现有的电缆防火性能的不足，本发明提供了一种稳定型防火电缆。
本发明解决其技术问题所采用的技术方案是：一种稳定型防火电缆，由内到外依次为电缆导体、屏蔽层、防火层、绝缘层、防腐层和保护层，电缆导体为铜丝螺旋绞合组成，提高了电缆整体的柔韧性。
根据本发明的另一个实施例，进一步包括防火层内部由支撑架和玻璃纤维组成，支撑架为防火层提供了支撑作用，保护了防火层的防火材料玻璃纤维的整体稳定性。
根据本发明的另一个实施例，进一步包括防腐层为加强筋和陶瓷纤维组成，加强筋增强了结构的稳定性。
本发明的有益效果是，此设计结构简单，具有优良的抗干扰性能、防火性能、柔软性能，提高了电缆的整体结构紧凑性，延长了线缆使用寿命。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图；
图中1、电缆导体，2、屏蔽层，3、防火层，31、支撑架，4、绝缘层，5、防腐层，51、加强筋，6、保护层。
具体实施方式
如图1是本发明的结构示意图，一种稳定型防火电缆，由内到外依次为电缆导体1、屏蔽层2、防火层3、绝缘层4、防腐层5和保护层6，电缆导体1为铜丝螺旋绞合组成，提高了电缆整体的柔韧性。屏蔽层2采用聚对苯二甲酸乙二醇酯塑料制成。防火层3内部由支撑架31和玻璃纤维组成，支撑架31为防火层3提供了支撑作用，保护了防火层3的防火材料玻璃纤维的整体稳定性。绝缘层4为合成云母带重叠绕包制成。防腐层5为加强筋51和陶瓷纤维组成，加强筋51增强了结构的稳定性。保护层6采用低烟无卤阻燃聚烯烃材料，在燃烧时不会释放有毒气体，无毒环保，同时具有较好的耐酸碱、耐候性能，对电缆起到较好的保护作用。
