Abstract

本实用新型涉及一种电力电缆生产技术领域,本实用新型阻水型电力电缆设有三组线蕊,每组线蕊由导体、橡胶层和绝缘层组成,橡胶层涂覆在导体外,绝缘层挤包在涂覆的橡胶层外,在三组线蕊和填充层外绕包阻水内绕包层,在所述阻水内绕包层外从内向外依次设置聚乙烯内衬层、铜带屏蔽层、外绕包层、铝-聚粘结护层和外护层。由于在三组线蕊和填充层外绕包阻水内绕包层,使本实用新型产品具有优异的阻水性能和电性能,即使水份渗入外护层,或护套发生破损,也不会对线蕊造成信号干扰,以保障电力电缆的正常使用。

Description

阻水型电力电缆
技术领域
本实用新型涉及一种电力电缆生产技术领域,具体涉及一种阻水型电力电缆。 
背景技术
普通电缆本身不具备阻水特性,在地下水位较高或常年多雨地区水分很容易渗入护套或从护套的破损处侵入到电缆内部,并引发事故,为此,越来越多的用户对电缆提出了阻水要求。 
发明内容
本实用新型是为了克服普通电缆的不足,提供一种具有防止水分渗入护套或从护套的破损处侵入到电缆内部的阻水型电力电缆。 
本实用新型设有三组线蕊,每组线蕊由导体、橡胶层和绝缘层组成,橡胶层涂覆在导体外,绝缘层挤包在涂覆的橡胶层外,在三组线蕊和填充层外绕包阻水带绕包层,在所述阻水带绕包层外从内向外依次设置聚乙烯内衬层、铜带屏蔽层、外绕包层、铝-聚粘结护层和外护层。 
本实用新型结构合理,不但考虑电缆的径向渗透,而且考虑到有效阻止水分侵入电缆后沿电缆纵向扩散。本实用新型产品具有优异的阻水性能和电性能,有效地保障了电力电缆的正常使用。 
附图说明
图1为是本实用新型的结构示意图。 
具体实施方式
如图1所示,本实用新型设有三组线蕊,每组线蕊由导体1、橡胶层2和绝缘层3组成,橡胶层2涂覆在导体1外,绝缘层3挤包在涂覆的橡胶层2外。在三组线蕊和填充层4外绕包阻水带绕包层5成缆,在缆芯绕包层5外从内向外依次设置聚乙烯内衬层6、铜带屏蔽层7、外绕包层8、铝-聚粘结护层9和外护层10。
