本实用新型是通过下述技术方案来解决上述技术问题的：一种煤矿用聚乙烯绝缘钢丝编织铠装通信电缆，其特征在于，其包括导体、聚乙烯绝缘层、包带、成缆包带、聚乙烯内护套、铠装层、阻燃外护套，铠装层位于聚乙烯内护套和阻燃外护套之间，成缆包带位于聚乙烯内护套的内侧，包带位于成缆包带的内侧，导体、聚乙烯绝缘层都位于包带内。
优选地，所述铠装层采用钢丝编织铠装结构。
本实用新型的积极进步效果在于：本实用新型的铠装层采用钢丝编织铠装结构，主要应用在机械冲击较高的矿井平巷和斜巷作主信号传输，铠装层可防止机械冲击对电缆造成损害。
附图说明
图1为本实用新型煤矿用聚乙烯绝缘钢丝编织铠装通信电缆的结构示意图。
具体实施方式
下面结合附图给出本实用新型较佳实施例，以详细说明本实用新型的技术方案。
如图1所示，本实用新型煤矿用聚乙烯绝缘钢丝编织铠装通信电缆包括导体1、聚乙烯绝缘层2、包带3、成缆包带4、聚乙烯内护套5、铠装层6、阻燃外护套7，铠装层6位于聚乙烯内护套5和阻燃外护套7之间，成缆包带4位于聚乙烯内护套5的内侧，包带3位于成缆包带4的内侧，导体1、聚乙烯绝缘层2都位于包带3内。铠装层采用钢丝编织铠装结构。
本实用新型的铠装层采用钢丝编织铠装结构，主要应用在电声干扰较大的场所作信号传输，适用于固定敷设，铠装层可对干扰信号进行有效屏蔽，防止误信号的传输。每一个绞合线对进行同心绞合成缆。阻燃外护套采用阻燃材料。每两根导体及其绝缘层绞合成一个线对，每个线对的绞合节距不同，这样可使信号的传输性能更加优异。本实用新型的铠装层采用钢丝编织铠装结构，主要应用在电声干扰较大的场所作信号传输，适用于固定敷设，铠装层可对干扰信号进行有效屏蔽，防止误信号的传输主要应用在机械冲击较高的矿井平巷和斜巷作主信号传输，铠装层可防止机械冲击对电缆造成损害。
