Description
—种双屏蔽耐火电缆
技术领域
[0001 ] 本实用新型涉及电缆技术领域，提供了 一种双屏蔽耐火电缆。
背景技术
[0002] 电缆在轻轨、地铁或室内敷设时，对其阻燃、耐火性能提出了很高要求。为了满足电缆使用环境的要求，根据不同的阻燃、耐火要求设计产品结构。目前广泛使用的铁路信号电缆、铁路数字信号电缆、铁路内屏蔽数字信号电缆、轨道交通信号电缆、应答器数据传输电缆等分为两大类，一是综合护套结构，二是铝护套结构。其抗屏蔽能力差，防水耐火能力弱。
[0003] 自1836年世界上生产出第一条低压电力电缆(橡皮带绕包铜导线)至今，电线电缆已经发展成为用途广泛、品种繁多的一大产品类别。我国电线电缆行业经过70多年的发展，也取得了较大的进步。伴随着中国电线电缆行业高速发展，新增企业数量不断上升，行业整体技术水平得到大幅提高。目前我国电线电缆行业国有及规模以上企业约5000家，其中大型企业有19家，总产值占整个市场份额的11%。
[0004] 电线电缆是输送能源、传递信息所不可缺少的基础器材，从在社会信息化、电气化快速发展的今天，电线电缆已成为经济建设中最重要的基础产品之一。电线电缆行业又是配套行业，产品必须满足国民经济各主行业对电线电缆性能的要求，国民经济觉得多数行业都与电线电缆相关，其产业地位是十分重要的。我国电线电缆行业目前仍处在发展阶段，作为国民经济建设重要先导行业，电线电缆产销指标的增长一般比国民经济总产值要略高一些。
发明内容
[0005] 本发明的目的在于提供一种屏蔽性能强，耐高温能力好的一种双屏蔽耐火电缆。
[0006] 为了实现上述目的本实用新型采用以下技术方案:
[0007] 一种双屏蔽耐火电缆，其特征在于:包括至少3根导体1，导体外均包裹绝缘层2，所有包裹有绝缘层2的导体I被内屏蔽层3包裹，内屏蔽层3与绝缘层2间的空隙处填充填料物4，内屏蔽层3外包裹外屏蔽层5，外屏蔽层5外包裹阻燃层6，阻燃层6外包裹护套层7，所述内屏蔽层和外屏蔽层均包括铜箔，铜箔两面均设有铝箔。
[0008] 所述填充填料物4为耐火阻水带，其包括云母层，云母层两面分别粘接玻璃纤维网格编制的补强层，在补强层上粘接一层由阻水粉构成的薄膜形成阻水层。
[0009] 所述填充填料物4为玻璃纤维。
[0010] 所述填充填料物4为橡胶。
[0011] 所述阻燃层6包括云母层和玄武岩纤维编织层，所述云母层厚度为0.2-0.9mm，玄武岩纤维编织层能够很好的将云母包裹，使得云母在受热时不分离。
[0012] 所述玄武岩编织层，单丝直径为0.2-0.9mm。
[0013] 因为本实用新型采用以上技术方案，所以具备以下有益效果:[0014] 通过内屏蔽和外屏蔽使得电缆获得较高的抗静电干扰、抗外磁场干扰、抗射频干扰能力，防水耐火能力强。
附图说明
[0015] 图1为本实用新型的结构图。
具体实施方式
[0016] 一种双屏蔽耐火电缆，其特征在于:包括至少3根导体1，导体外均包裹绝缘层2，所有包裹有绝缘层2的导体I被内屏蔽层3包裹，内屏蔽层3与绝缘层2间的空隙处填充填料物4，内屏蔽层3外包裹外屏蔽层5，外屏蔽层5外包裹阻燃层6，阻燃层6外包裹护套层7，所述内屏蔽层和外屏蔽层均包括铜箔，铜箔两面均设有铝箔。
[0017] 所述填充填料物4为耐火阻水带，其包括云母层，云母层两面分别粘接玻璃纤维网格编制的补强层，在补强层上粘接一层由阻水粉构成的薄膜形成阻水层。
[0018] 所述填充填料物4为玻璃纤维。
[0019] 所述填充填料物4为橡胶。
[0020] 所述阻燃层6包括云母层和玄武岩纤维编织层，所述云母层厚度为0.2-0.9mm。
[0021] 所述玄武岩编织层，单丝直径为0.2-0.9mm。
