Abstract

本实用新型公开了一种全阻水海底电力电缆,包括有主导体、辅线芯导体和动力线芯导体,所述的主导体、辅线芯导体和动力线芯导体外侧分别包有屏蔽绝缘层,将四个动力线芯导体两两相切放置且包有绕包层构成动力线芯,在动力线芯外侧分布有两个辅线芯导体并包有包带层构成辅线芯,将四个辅线芯两两相切放置且在每两个辅线芯之间和四个辅线芯之间分别设有主导体,外侧依次包覆有密封胶、半导电阻水带、内衬层、阻水缓冲层、防腐层和外护套。本实用新型通过设有密封胶、半导体阻水带、阻水缓冲层,可以达到很好的阻水效果,且不容易被腐蚀,使用寿命长,节约资源,经济实用。

Description

一种全阻水海底电力电缆
技术领域
    本实用新型涉及电缆技术领域,尤其涉及一种全阻水海底电力电缆。
背景技术
    目前,海底电力电缆导体的纵向阻水主要依靠向导体各绞层间加入阻水粉或阻水纱来实现,这种结构不仅阻水效果不好,且不能防腐蚀,长期在水里浸泡容易腐烂且容易断裂。
实用新型内容
本实用新型目的就是为了弥补已有技术的缺陷,提供一种全阻水海底电力电缆。
本实用新型是通过以下技术方案实现的:
一种全阻水海底电力电缆,包括有主导体、辅线芯导体和动力线芯导体,所述的主导体、辅线芯导体和动力线芯导体外侧分别包有屏蔽绝缘层,将四个动力线芯导体两两相切放置且包有绕包层构成动力线芯,在动力线芯外侧分布有两个辅线芯导体并包有包带层构成辅线芯,将四个辅线芯两两相切放置且在每两个辅线芯之间和四个辅线芯之间分别设有主导体,外侧依次包覆有密封胶、半导电阻水带、内衬层、阻水缓冲层、防腐层和外护套。
本实用新型的优点是:本实用新型通过设有密封胶、半导体阻水带、阻水缓冲层,可以达到很好的阻水效果,且不容易被腐蚀,使用寿命长,节约资源,经济实用。
附图说明
    图1为本实用新型的结构示意图。
具体实施方式
如图1所示,一种全阻水海底电力电缆,包括有主导体1、辅线芯导体2和动力线芯导体3,所述的主导体1、辅线芯导体2和动力线芯导体3外侧分别包有屏蔽绝缘层4,将四个动力线芯导体3两两相切放置且包有绕包层5构成动力线芯,在动力线芯外侧分布有两个辅线芯导体2并包有包带层6构成辅线芯,将四个辅线芯两两相切放置且在每两个辅线芯之间和四个辅线芯之间分别设有主导体1,外侧依次包覆有密封胶7、半导电阻水带8、内衬层9、阻水缓冲层10、防腐层11和外护套12。
