Abstract

本实用新型公开了一种阻水架空绝缘电缆，它包括绝缘套，在绝缘套内设有多层导体，其特殊之处是：在绝缘套内位于相邻两层导体之间分别设有阻水层，阻水层是由半导电阻水带沿纵向包裹在导体上形成。优点是：由于在绝缘套内位于相邻两层导体之间分别设有阻水层，阻水层是由半导电阻水带沿纵向包裹在导体上形成，因此纵向阻水效果好，工艺简单，生产效率高，成本低；电缆导体不易氧化，绝缘套不易产生水树，使用寿命长，能够保证城市电网的正常运行。

Description

阻水架空绝缘电缆
技术领域
本实用新型属于一种电缆，特别涉及一种在能够在潮湿环境下工作的阻水架空绝缘电缆。
背景技术
现有的城市电网输电线路采用的主要电缆为架空绝缘电缆，在潮湿环境下工作的架空绝缘电缆极易造成端部进水，由于电缆绝缘的存在，进入电缆内部的水分不易散发，长期存于电缆内部，与导体产生氧化反应而腐蚀导体，损耗加大。而且绝缘套吸水后会产生水树，使得运行中的电缆绝缘层发生击穿而损坏，使电缆的寿命降低，影响城市电网的正常运行。
发明内容
本实用新型所要解决的技术问题是要提供一种阻水效果好，使用寿命长的阻水架空绝缘电缆。
本实用新型是这样实现的：它包括绝缘套，在绝缘套内设有多层导体，其特殊之处是：在绝缘套内位于相邻两层导体之间分别设有阻水层，阻水层是由半导电阻水带沿纵向包裹在导体上形成。
本实用新型的优点是：由于在绝缘套内位于相邻两层导体之间分别设有阻水层，阻水层是由半导电阻水带沿纵向包裹在导体上形成，因此纵向阻水效果好，工艺简单，生产效率高，成本低；电缆导体不易氧化，绝缘套不易产生水树，使用寿命长，能够保证城市电网的正常运行。
附图说明
图1是本实用新型的结构示意图。
图中： 1-绝缘套，2-导体，3-阻水层。
具体实施方式
如图所示，该阻水架空绝缘电缆包括绝缘套1，在绝缘套1内设有相互绞合的多层导体2，本实施例以四层为例，其中最内层导体2位于绝缘套1内的中心处，在绝缘套1内位于相邻两层导体2之间分别设有阻水层3，阻水层3是由半导电阻水带沿纵向包裹在导体2上形成。
