Description

1kV山区用耐气候阻水架空绝缘电缆
技术领域
本发明属于电缆领域，具体涉及一种1kV山区用耐气候阻水架空绝缘电缆。
背景技术
公告号为CN207458643U、公告日为2018.06.05的中国实用新型专利公开了一种新型高抗拉架空绝缘电缆，包括相线线芯、中性线芯和连接筋，相线线芯包括相导体、绕包在相导体外侧的包带和设置在包带外侧的相线绝缘层，中性线芯包括中性线导体和设置在中性线导体外侧的中性线绝缘层，相线绝缘层和中性线绝缘层采用耐候交联聚乙烯。交联聚乙烯绝缘材料具有较好的耐热性能、绝缘性能、机械特性和耐化学特性，非常符合架空电缆的使用要求，但是对水分较为敏感，水分浸入后在高电压下会形成“水树枝”，导致绝缘破坏，容易引发事故。
发明内容
本发明的目的在于提供一种具有良好阻水性能的1kV山区用耐气候阻水架空绝缘电缆。
为实现上述目的，本发明的1kV山区用耐气候阻水架空绝缘电缆采用以下的技术方案：1kV山区用耐气候阻水架空绝缘电缆包括相线芯、中性线芯和连接在相线芯与中性线芯之间的连接筋，相线芯包括相导体，相导体外侧依次设置包带和相线绝缘层，相线绝缘层为耐候性交联聚乙烯绝缘料，包带内部设有阻水填充。
有益效果：包带将相导体与相线绝缘层隔开，阻水填充在包带内部起到良好的阻水作用，使得耐候性交联聚乙烯绝缘料的相线绝缘层能够更好的工作；相比于现有技术，得到阻水性能较好的耐气候阻水架空绝缘电缆，提高电缆安全性能。
进一步的，阻水填充包括阻水沙，阻水沙有效填充包带内的间隔且阻水效果较好。
进一步的，包带为阻水包带，阻水包带与阻水沙配合，进一步提高电缆阻水能力。
进一步的，包带厚度为相导体半径的1/2-2/3。
进一步的，相线芯的直径大于中性线芯的直径。
附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其它的附图；
图1是本发明的1kV山区用耐气候阻水架空绝缘电缆的具体实施例的结构示意图。
图中：1-相导体、2-阻水沙、3-包带、4-铝丝、5-相线绝缘层、6-中性导体、7-中性线绝缘层、8-连接筋。
具体实施方式
为了使本发明的技术目的、技术方案和有益效果更加清楚，下面结合附图和具体实施例对本发明的技术方案作出进一步的说明。
如图1所示，1kV山区用耐气候阻水架空绝缘电缆包括相线芯、中性线芯和连接在两者之间的连接筋8，相线芯包括相导体1，相导体1外依次设置包带3和相线绝缘层5，中性线芯包括中性导体6和中性线绝缘层7，相线绝缘层5、中性线绝缘层7和连接筋8采用耐候性交联聚乙烯绝缘料，相线芯直径大于中性线芯直径，相线绝缘层5中嵌入铝丝4，构成抗拉结构。
相导体1采用绞合8000系铝合金导体，中性导体6采用铝合金绞线，包带3为丙纶丝，包带3厚度为相导体1横截面半径的1/2-2/3，包带3内部设有填充阻水沙2。包带3将相导体1与相线绝缘层5隔开，阻水沙2填充起到良好的阻水作用，使相线绝缘层工作更加安全；相比于现有技术，得到阻水性能较好的耐气候阻水架空绝缘电缆。
在其他实施例中，也可以用阻水纱、阻水膏代替阻水沙，或者几种阻水填充同时使用，达到较好的阻水效果，同时包带也可以采用阻水带，阻水包带与阻水沙配合，进一步提高电缆阻水能力。
最后所应说明的是：上述实施例仅用于说明而非限制本发明的技术方案，任何对本发明进行的等同替换及不脱离本发明精神和范围的修改或局部替换，其均应涵盖在本发明权利要求保护的范围之内。
