Description
技术领域
本实用新型涉及一种电缆技术领域，尤其涉及一种抗延伸聚太阳能型铝芯交联电力电缆。
背景技术
交联聚乙烯电缆绝缘电缆是近几年发展起来的极有前途的塑料电缆。这种电缆具有电场分布均匀、重量轻、载流量大的特点。传统的铝芯交联电缆，在抗拉强度上面受到很大的限制，并且电缆要是在夜间发生故障，维修有相当大的难度。专利号为200820003774.X的专利公开了一种发光矿用电缆，对原矿用井下电缆的外护套进行改进，使其具有发光功能，便于在黑暗的环境下进行维修，但是此类电缆应用范围窄，抗拉抗压强度较弱，载流量小。
实用新型内容
本实用新型为了解决以上问题提供了一种机械性能好、可发光的抗延伸聚太阳能型铝芯交联电力电缆。
本实用新型的技术方案是：包括成缆线芯和发光护套层，所述的成缆线芯由铝导体、交联聚乙烯绝缘层、聚丙烯填充料和绕包带绞合而成，所述的交联聚乙烯绝缘层内挤包掺有发光层，所述的护套层内在线芯周围均匀放置若干根芳纶纤维。
所述的发光层为稀土硼酸盐蓄光性发光粉层。
本实用新型在可见光、紫外线等光源存在时，能将光能储蓄起来，在黑暗状态下，再将所储蓄的光能缓慢释放出来产生荧光，达到漆黑的环境条件下发光的目的，便于电缆的检修和维护，线芯周围均匀放置若干根芳纶纤维大大增强了电缆的抗拉伸性能。
本实用新型结构合理筒单，生产制造容易。重量轻、介质损耗小、传输能力强、耐拉、操作和维护方面等优点，可广泛用于城市地下电网、发电站的引出线路、工矿企业的内部供电及过江、过海的水下输电线。随着工农业生产中自动化程度的日益提高，这类产品的用量将愈来愈多。
附图说明
图1是本实用新型的结构示意图。
图中1是导体，2是绝缘层，3是填充料，4是绕包带，5是芳纶纤维，6是护套层。
具体实施方式
抗延伸聚太阳能型铝芯交联电力电缆，包括成缆线芯和发光护套层6，所述的成缆线芯由铝导体1、交联聚乙烯绝缘层2、聚丙烯填充料3和绕包带4绞合而成，所述的交联聚乙烯绝缘层2内挤包掺有发光层，所述的护套层6内在线芯周围均匀放置若干根芳纶纤维5，所述的发光层为稀土硼酸盐蓄光性发光粉层。
