Description

一种耐火环保电缆
技术领域
本发明属于电缆领域，尤其涉及一种耐火环保电缆。
背景技术
耐火环保电缆是最常见的一种电缆，使用范围广。但是随着现在用电领域的扩大，人们对电缆的耐火环保屏蔽功能要求越来越搞，一般耐火环保电缆无屏蔽层、起火后因线芯温度过高导致其他材料融化、也不能阻止火焰对电缆持续的破坏。
发明内容
针对现有电缆存在的缺陷，本发明提出一种耐火环保电缆，屏蔽性好，能防止火焰二次破坏。
为了实现上述目的，本发明提出一种耐火环保电缆，它包括导线线芯、耐火环保云母带、线芯绝缘层、加固层、加固填充物、耐火填充物、耐火包带、内护套、金属屏蔽层、外护套；所述导线线芯共设置七组；所述线芯包括线芯导体、耐火环保云母带、线芯绝缘层；所述耐火环保云母带包覆线芯导体；耐火环保云母带外部包裹着所述线芯绝缘层；七组线芯均匀挤包在所述加固层内部；加固层外部包裹所述耐火包带；耐火包带外部包裹所述内护套；内护套外部包裹所述金属屏蔽层；金属屏蔽层外部包裹所述外护套；外护套、金属屏蔽层、内护套、耐火包带、加固层位于同一中心轴上；所述加固填充物填充在加固层与导线线芯之间；所述耐火填充物填充在加固层与耐火包带之间。
所述加固层为正多边形。
所述耐火填充物为聚碳酸酯树脂。
所述外护套为聚乙烯。
综合所述本发明有以下有益效果：耐火环保性好、屏蔽性高、提高了电缆强度、防止了火焰对电缆的二次破坏。
附图说明
图1为本发明横截面结构示意图。
具体实施方式
如图1所示，它包括导线线芯、耐火环保云母带2、线芯绝缘层3、加固层4、加固填充物5、耐火填充物6、耐火包带7、内护套8、金属屏蔽层9、外护套10；导线线芯共设置七组；导线线芯包括线芯导体1、耐火环保云母带2、线芯绝缘层3；耐火环保云母带2包覆线芯导体1；耐火环保云母带2外部包裹着线芯绝缘层3；七组导线线芯均匀挤包在所述加固层内部4；加固层4外部包裹耐火包带7；耐火包带7外部包裹内护套8；内护套8外部包裹金属屏蔽层9；金属屏蔽层9外部包裹外护套10；外护套10、金属屏蔽层9、内护套8、耐火包带7、加固层4位于同一中心轴上；加固填充物5填充在加固层4与导线线芯之间；耐火填充物6填充在加固层4与耐火包带7之间。
具体实施：加固层4为正多边形。
耐火填充物6为聚碳酸酯树脂。
外护套10为聚乙烯。
以上所述是本发明实施例，故凡依本发明申请范围所述的构造、特征及原理所做的等效变化或修饰，均包括于本发明专利申请范围内。
