Description

一种0.6/1kv铜芯交联聚乙烯绝缘聚氯乙烯护套阻水电力 电缆
技术领域
本发明涉及电线电缆领域，具体涉及一种0.6/1kv铜芯交联聚乙烯绝缘聚氯乙烯护套阻水电力电缆。
背景技术
随着科技的进步和社会的发展，众多集团化企业、高层建筑、公共娱乐场所、地铁及地下街道等不断涌现，其用电量与日俱增，各类电缆的品种及用量也相应增加。然而普通电缆不能同时承受机械外力和进行有效防水，在许多重要场合中，一旦电缆受到损伤或进水就导致供电、通信等系统无法运行甚至发生事故时，给正常的社会生活带来不便。
在高压电缆中，导体表面不光洁，表面有缝隙和毛刺，对电缆造成不良的影响，柔软性，抗拉性，抗老化，耐腐蚀性差。
发明内容
为了克服现有技术中存在的不足，提供一种具有很好的柔软性，抗拉性，抗老化，耐腐蚀性的额定电压0.6/1kv铜芯交联聚乙烯绝缘聚氯乙烯护套阻水电力电缆。
为实现上述目的，本发明提供一种0.6/1kv铜芯交联聚乙烯绝缘聚氯乙烯护套阻水电力电缆，包括位于电缆最中心的多个分割紧压铜导体，在每个分割紧压铜导体间设有阻水带，在分割紧压铜导体表面绕包无纺布，在无纺布外挤包绝缘层，在绝缘层外挤包外护套。
优选地，所述的分割紧压铜导体由多块铜股块紧压而成，提高了绞合导体的表面质量，缩小导体直径，减少绞线中单线之间空隙，改善电缆电场均匀分布起到良好的作用，增加了中压电缆的使用可靠性。
优选地，所述的绝缘层为硅烷交联聚乙烯绝缘层。
优选地，所述的外护套为弹性体PVC护套。
本发明的有益效果在于：
与现有技术相比，本发明的结构简单，为了提高导体表面的光洁度、防止导体表面缝隙和毛刺对电缆绝缘的不良影响、防止内屏蔽料陷入导体，同时也为了节省材料、降低成本，导体多采用分割式，在分割导体间设有阻水带，保护了每个导体不受水分的影响；并且在导体表面还绕包无纺布，提高电缆的阻水性；本发明还具有很好的柔软性，抗拉性，抗老化，耐腐蚀性。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合附图和具体实施例，进一步阐明本发明，应理解这些实施例仅用于说明本发明而不用于限制本发明的范围，在阅读了本发明之后，本领域技术人员对本发明的各种等价形式的修改均落于本申请所附权利要求所限定的范围。
如图1所示，本发明提供一种0.6/1kv铜芯交联聚乙烯绝缘聚氯乙烯护套阻水电力电缆，包括位于电缆最中心的多个分割紧压铜导体1，在每个分割紧压铜导体间设有阻水带2，在分割紧压铜导体表面绕包无纺布3，在无纺布外挤包绝缘层4，在绝缘层外挤包外护套5。
所述的分割紧压铜导体由多块铜股块紧压而成，提高了绞合导体的表面质量，缩小导体直径，减少绞线中单线之间空隙，改善电缆电场均匀分布起到良好的作用，增加了中压电缆的使用可靠性。
所述的绝缘层为硅烷交联聚乙烯绝缘层，抗老化性强，拉伸强度高，使用寿命长。
所述的外护套为弹性体PVC护套，使得电缆更加的柔软。
以上所述仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干变型和改进，这些也应视为属于本发明的保护范围。
