Description

一种镀银钢带屏蔽电力电缆
技术领域
本发明属于电缆领域，尤其涉及一种镀银钢带屏蔽电力电缆。
背景技术
随着我国工业的不断发展，目前我国已全面进入电气化时代，电力电缆使用量也越来越大，制造电缆的导体主要成分是铜，占总用铜量的约70%。但我国铜资源非常短缺，随着中国铜矿资源的枯竭，中国铜矿80%需要进口，依赖性大。随着铜价的不断攀升，以铝代替铜是电线电缆发展的必然趋势。法国的电线电缆80%以上为镀银铜导体，日本的铝导线也占50%以上。我国铝资源十分丰富，但应用量不到1%，主要还是因为铝导线制造技术的不成熟所致，因此获得技术上的突破是解决这一问题的关键。
过去镀银铜导体电线电缆，由于铝的强度和延伸率等机械性能满足不了要求，同时又没有阻水作用。所以迄今为止还没有一种具有价格低廉性能优异的又有阻水性能的0.6/1kV电力电缆。
发明内容
本专利是为避免上述现有技术所存在的不足之处，提供一种柔软程度好，线芯不易断裂，又具有抗弯曲、耐腐蚀、阻燃、防水等特性的移动电缆，以适应移动的工作环境的镀银钢带屏蔽电力电缆。
本发明是采取以下技术方案来实现的：一种镀银钢带屏蔽电力电缆，它是由控制线芯、接地线芯、镀银钢带铠装层、镀银钢带屏蔽层、镀银铜带屏蔽层、低烟无卤护套层以及聚氯乙烯护套层组成，所述控制线芯设置有三组，它是由镀银铜导体、丁腈绝缘层以及镀银铜丝屏蔽层组成，所述接地线芯设置有一组，它是由镀银铜导体、丁腈绝缘层以及镀锌铜丝屏蔽层组成，所述控制线芯以及接地线芯挤包在镀银钢带铠装层内部，所述镀银钢带铠装层之外包裹一层镀银钢带屏蔽层，所述镀银钢带屏蔽层之外包裹一层镀银铜带屏蔽层，所述镀银铜带屏蔽层之外包裹一层聚氯乙烯绝缘层，所述聚氯乙烯绝缘层之外包裹一层低烟无卤护套层，所述低烟无卤护套层之外包裹一层聚氯乙烯护套层。
所述镀银铜导体横截面直径长为3毫米，所述镀银铜导体横截面直径长为1.5毫米。
综上所述本发明具有以下有益效果：本发明具有抗蠕变、高柔韧、强延展、低反弹、连接稳定、阻水性能好等优点，另一方面还降低了电缆的成本50%。
附图说明
图 1为本发明横截面结构示意图。
具体实施方式
