Description

高柔韧性抗拉型通信电缆
技术领域
本发明涉及一种通信电源缆，尤其涉及一种高柔韧性抗拉型通信电缆。
背景技术
通信电源用软电缆是一种通信设施的供电连接线，在电信局站、配电箱柜之类的配电系统中广泛使用。通信电源用软电缆不仅要求具有良好的柔软性，以便在狭窄的空间内或类似的情形下方便敷设，而且要求具有理想的阻燃性，以适应防火等级严苛场合下的使用要求。并非限于上面例举的通信电源用软电缆虽然各有相应的技术效果，但是存在以下共同的缺憾：其一，由于均是以绞合细铜丝作为导体的，并且这种导体被业界称为五类铜导体，因而柔软程度并不能满足期望的要求。并且由于柔软度差而使弯曲半径受到限制，因而在狭窄空间、受不可移动的物体阻碍乃至拐弯抹角处之类的场合敷设时，极易影响施工速度；其二，由于在技术偏见下普遍择用铜作为软电缆的导体，因而不仅存在合理使用原材料方面的盲目性，而且导致软电缆的制造成本大；其三，由于份量重，因而不仅物流运输、仓储环节中的成本高，而且在敷设过程中施工人员劳动强度大，所耗人工成本高。
发明内容
本发明提供一种高柔韧性抗拉型通信电缆，该通信电缆提高了材料阻燃性能，代表阻燃性的氧指数极高，并且使得材料在燃烧时具有良好的成炭效果，也提高了电缆的导电性能、弯曲性能和耐腐蚀性能，且减小了安装布局的空间和安装成本。
为达到上述目的，本发明采用的技术方案是：一种高柔韧性抗拉型通信电缆，包括三个导电线芯，此导电线芯进一步包括圆形芳纶纤维芯，此圆形芳纶纤维芯外表面绞合有若干根第一铝合金圆导体，且若干根所述第一铝合金圆导体形成内导电层，此内导电层外表面绞合有若干根第二铝合金圆导体，且若干根所述第二铝合金圆导体形成外导电层，一聚乙烯绝缘带绕包于所述外导电层外表面；
所述聚乙烯绝缘带外表面包覆有一聚氯乙烯内衬层，一阻燃聚烯烃弹性护套层位于所述聚氯乙烯内衬层外表面，所述聚氯乙烯内衬层和阻燃聚烯烃弹性护套层之间设置有PVC发泡绝缘层；
所述圆形芳纶纤维芯由若干根芳纶纤维丝绞合而成；一耐火云母带绕包覆于三个所述导电线芯外表面，所述耐火云母带外表面包覆有绝缘护套层，所述绝缘护套层由以下组分组成：热塑性聚氨酚弹性体80~100份、熔融指数为1~8g/10min的低密度聚乙烯10~20份、乙烯丙烯酸乙酯13份、乙烯丁烯共聚物7份、二氧化硅7份、丁腈复合物16份、氯化聚乙烯6份、锡酸锌8.5份、氢氧化镁5~12份、复合钼抑烟剂2~8份、蒙脱土1~5份、钙锌复合稳定剂 1~3份、双（3，5-三级丁基-4-羟基苯基）硫醚1~3份、硬脂酸锌2~4份。
上述技术方案中进一步改进的技术方案如下：
上述方案中，所述耐火云母带与导电线芯之间填充有若干根PP 填充绳。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
1. 本发明高柔韧性抗拉型通信电缆，采用2层导电层，内导电层由若干个“Z”字形导体绞合而成，外导电层由若干个梯形导体绞合而成，其大大减少了涡流，减少线路的损耗，提高了电缆的导电性能、弯曲性能和耐腐蚀性能，减少了线缆发热量，能够保证电缆在长时间过载和过热时保持连续电气性能稳定。
2. 本发明高柔韧性抗拉型通信电缆，其绝缘护套层包括热塑性聚氨酚弹性体80~100份，搭配的熔融指数为1~8g/10min的低密度聚乙烯，乙烯丙烯酸乙酯，钙锌复合稳定剂，双（3，5-三级丁基-4-羟基苯基）硫醚，硬脂酸锌，乙烯丁烯共聚物，二氧化硅，氯化聚乙烯，使得第一护套层综合了各自的优点，提高了耐气候性和阻燃性能，稳定性效果、耐辐照的特性，同时提高了绝缘性能、表面耐磨性和表面硬度，表面雾面哑光效果优良并降低材料的收缩率；其次，绝缘护套层进一步含有锡酸锌，氢氧化镁，复合钼抑烟剂，蒙脱土并与其它组分协同作用，丁腈复合物，大提高了材料阻燃性能，代表阻燃性的氧指数极高，并且使得材料在燃烧时具有良好的成炭效果，形成了稳定的中空复合炭结构，阻止了材料的二次燃烧和火焰传播。
3. 本发明高柔韧性抗拉型通信电缆，其聚乙烯绝缘带外表面包覆有一聚氯乙烯内衬层，一阻燃聚烯烃弹性护套层位于所述聚氯乙烯内衬层外表面，所述聚氯乙烯内衬层和阻燃聚烯烃弹性护套层之间设置有PVC发泡绝缘层，使得软电缆，抗拉强度大、载流量高、柔韧性高、易弯曲，而且其结构紧密，最小弯曲半径下降至为4倍电缆直径，减小了安装布局的空间，减小了安装成本，更易于敷设。
