Description

一种交联聚乙烯绝缘、聚氯乙烯护套电力电缆
技术领域：
本实用新型涉及一种电缆，特别是一种交联聚乙烯绝缘、聚氯乙烯护套电力电缆。
背景技术：
随着工业自动化程度的不断提高，对电力电缆的性能要求相应提高。特别是很多重要的场合诸如高层建筑、宾馆、铁路等的重要线路要求采用安全清洁耐火电力电缆。
发明内容：
本实用新型的发明目的旨在提供一种交联聚乙烯绝缘、聚氯乙烯护套电力电缆，以满足市场对安全清洁耐火电力电缆的需求。
实现上述发明目的的技术方案是：一种交联聚乙烯绝缘、聚氯乙烯护套电力电缆，其包括：
四根芯线，该芯线包括位于中间为多股软导体、依次包围在多股软导体外的耐火层和交联聚乙烯绝缘层；四根芯线的外周依次包围有一绕包层和一护套，在绕包层内、四根芯线外的间隙中设有填充层；所述护套为聚氯乙烯护套。
其中，所述软导体为多股镀锡铜丝束。
其中，所述耐火层由云母带绕包而成。
其中，所述绕包层为玻璃纤维带构成。
发明的有益效果：
依照本实用新型，其芯线外的绝缘层采用交联聚乙烯绝缘，电缆最外层的护套采用聚氯乙烯护套，除了能在正常条件下传输电力外，还能在火灾发生时的一段时间内安全运行。即在额定电压0.6/1KV供电条件下，并且处于750～800℃的火焰燃烧中，能维持90分钟的正常进行。同时，该电力电缆还具有低毒、低烟、无卤或低卤、阻燃安全清洁等特性，满足了当前市场对安全清洁耐火电缆的需求。
附图说明：
图1为本实用新型所述电缆的横截面结构示意图。
具体实施方式：
参见附图1，本实施例中，该电缆具有四根芯线10，芯线10中央采用多股软导体1，在软导体1的表面为耐火层2，耐火层2的外周是绝缘层3，四根芯线10嵌设在填充层4中，在填充层4外周是绕包层5，最外层为绝缘护套6。
其中，多股软导体1为镀锡铜丝束，耐火层2为云母带，填充层4由聚丙乙烯网状带填充，绕包层5为玻璃纤维带，交联聚乙烯绝缘层3为压塑机连续挤压成型，聚氯乙烯护套6也是压塑机连续挤压成型。本实用新型不仅具有耐火耐高温的特性，还具有低毒、低烟、无卤或低卤、阻燃安全清洁等特性，满足了当前市场对安全清洁耐火电缆的需求。
