Description
技术领域
本发明涉及电力电缆领域,尤其是指一种椭圆加强型微孔防水防潮电缆。
背景技术
传统的BV型电线在民用、工业、商业、建筑等的环境中使用时,导体是实心导体,散热性能差,往往很多火灾都是因为电线本身发热,热量没及时散发,且绝缘层是聚氯乙烯材料,其透气性好、吸水、容易受潮,加速电线老化而导致电线故障,极易引发放电伤人、引发火灾等重大灾难。且传统的BV型电线单位长度铜材重量大,成本高,性价比低;导体的结构不合理,没有中心微孔;导体散热性能差,载流量小;BV型电线绝缘层透气性好、吸水、容易受潮,加速电线老化;单位长度的铜材重量大,且劳动力投入大,严重浪费国家资源和社会劳动力;在敷设中,电缆不易固定。
发明内容
本发明所要解决的技术问题是提供了一种散热快、防水防潮效果好、成本低的椭圆加强型微孔防水防潮电缆。
本发明所述的一种椭圆加强型微孔防水防潮电缆,包括缆芯,所述的缆芯是由一根防潮电线以及位列于防潮电线两侧的且处于同一平面上的加强芯、地线芯构成;在缆芯外设有椭圆形第一防潮层;在防潮电线、加强芯、地线芯及第一防潮层之间的空隙处填充阻水纱。
进一步改进,所述的防潮电线包括由内向外依次设有的微孔、不透水层、铝导体、绝缘层以及圆形第二防潮层。
进一步改进,所述的第一防潮层外设有多根固定凸槽,使得电缆在敷设中更好的固定。
进一步改进,所述的微孔与铝导体轴心同心设置。
进一步改进,所述的第一防潮层与第二防潮层结构相同,具有三层结构,中间为高密度交联聚乙烯层,内层为PE层,外层为沥青层。
进一步改进,所述的不透水层热塑性低密度聚乙烯材料制成。
本发明的有益效果在于:
1、本发明设有加强芯,提高了电缆的整体强度;
2、所述不透水层由热塑性低密度聚乙烯材料制成,当电缆遇到水分或置于潮湿的场合时,能有效的阻止水分的侵入,大大增加了电缆的使用寿命,也提高了电缆使用的性。
3、绝缘层和防潮层的电性能和机械性能各自得到了最佳发挥,互弥补,协同作用,防潮层弥补了绝缘层透气、易受潮的缺陷,且防潮层不仅充分发挥防潮作用,同时起到第二道绝缘的作用。
4、在微孔与导体之间设有不透水层,能有效的阻止水分的侵入,大大增加了电缆的使用寿命,也提高了电缆使用的性。
5、导体的表面积增大,进而增强电流传送的肌肤效应,使导体能承载更大的电流;导体与空气接触面积增大,散热快。
6、防潮层具有三层结构,中间为高密度交联聚乙烯层,内层为PE层,外层为沥青层,每层都具有很好的防水防潮的效果,使得电缆具有了三倍的防潮效果,大大增加了电缆的防潮性能。
7、性价比高,单位长度无铜材,载流量增加40%
以上,单位长度绝缘耗材至少减少10%,节约了国 家有限的资源。
