Description

额定电压35kV及以下风力发电传输用电缆
技术领域
本实用新型涉及一种电力电缆，尤其是额定电压35kV及以下的风力发电传输用电缆。
背景技术
现有额定电压35kV及以下风力发电传输用电缆由于使用环境恶劣，其绝缘层易受损坏而导致水份进入电缆内层，易损坏电缆，缩短使用寿命。
发明内容
为了克服现有额定电压35kV及以下风力发电传输用电缆的不足，本实用新型提供一种具有新型结构的额定电压35kV及以下风力发电传输用电缆。
本实用新型提供的额定电压35kV及以下风力发电传输用电缆包括缆芯及外护套，缆芯内具有绝缘导线和填充件，绝缘导线的导体外设有导体屏蔽层及绝缘层，在绝缘导线的绝缘层外依次包覆绝缘屏蔽层、阻水带层、金属屏蔽层。
为了提高本实用新型阻水性能和机械强度，在缆芯与外护套之间依次设有阻水绕包带层、加强层和内护层。
本实用新型的有益效果是：阻水性能好，机械强度高，适于在环境恶劣的场合使用，不易损坏、延长使用寿命。
附图说明
图1是本实用新型的横截面示意图。
在图1中，1、导体，2、导体屏蔽层，3、绝缘层，4、绝缘屏蔽层，5、阻水带层，6、金属屏蔽层，7、填充件，8、阻水绕包带层，9、加强层，10、内护层，11、外护套，12、绝缘导线，13、缆芯。
具体实施方式
参照图1，将铜丝绞合并对各层铜丝作阻水处理后制成导体1，在导体1外依次包覆导体屏蔽层2、交联聚乙烯绝缘层3、绝缘屏蔽层4、阻水带层5，采用铜带绕包的金属屏蔽层6制成绝缘导线12，然后将绝缘导线12与填充件7一起绞合制成缆芯13，再在缆芯13外包覆阻水绕包带层8，采用铝塑复合带纵包加强层9，采用聚乙烯包覆内护层10，采用聚胺酯电缆料包覆外护套11，即制成本实用新型。
