Description

煤矿用聚乙烯绝缘铜丝编织屏蔽通信电缆
技术领域
本实用新型涉及一种通信电缆，特别是涉及一种煤矿用聚乙烯绝缘铜丝编织屏蔽通信电缆。
背景技术
通信电缆是指传输电话、电报、传真文件、电视和广播节目、数据和其他电信号的电缆。现有通信电缆中会存在干扰信号，会有误信号的传输。
实用新型内容
本实用新型所要解决的技术问题是提供一种煤矿用聚乙烯绝缘铜丝编织屏蔽通信电缆，其屏蔽层可对干扰信号进行有效屏蔽，防止误信号的传输。
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铜丝编织屏蔽通信电缆，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、屏蔽层、阻燃外护套，屏蔽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，所述屏蔽层采用铜丝编织屏蔽结构。
本实用新型的积极进步效果在于：本实用新型的屏蔽层采用铜丝编织屏蔽结构，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，屏蔽层可对干扰信号进行有效屏蔽，防止误信号的传输。
附图说明
图1为本实用新型煤矿用聚乙烯绝缘铜丝编织屏蔽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铜丝编织屏蔽通信电缆包括导体1、聚乙烯绝缘层2、包带3、成缆包带4、聚乙烯内护套5、屏蔽层6、阻燃外护套7，屏蔽层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。屏蔽层采用铜丝编织屏蔽结构。
本实用新型的屏蔽层采用铜丝编织屏蔽结构，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，屏蔽层可对干扰信号进行有效屏蔽，防止误信号的传输。包带设有线芯。每两根导体及其聚乙烯绝缘层绞合成一个线对，位于一个同心圆内。导体的直径与聚乙烯绝缘层的直径相同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。每一个绞合线对进行绞合成缆。阻燃外护套采用阻燃材料。
以上所述的具体实施例，对本实用新型的解决的技术问题、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本实用新型的具体实施例而已，并不用于限制本实用新型，凡在本实用新型的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
