Abstract

一种耐寒型超5类数字通信实芯聚烯烃绝缘水平对绞电缆，包括缆芯及外护套，缆芯内具有数个导线对绞组，在缆芯与外护套之间设有内护套。由于本实用新型采用内护套和外护套的双护套结构，明显减小电缆的拉伸应变，其抗拉伸抗弯曲性能增强。本实用新型的双护套结构以及采用添加有增塑剂、稳定剂、耐寒剂的聚烯烃护套料制作外护套，使电缆的耐寒性能明显提高，适应在室外较寒冷的环境中使用，也可作为集散系统、自动化检测系统、计算机局域网机房中的数字传输电缆。

Description

耐寒型超5类数字通信实芯聚烯烃绝缘水平对绞电缆
技术领域
本实用新型涉及一种信号传输电缆，尤其是超5类数字通信电缆。
背景技术
现有超5类数字通信电缆，由于其结构和用材方面的原因，其抗拉伸抗弯曲和耐寒性能不理想，在室外较寒冷的环境中使用容易开裂受损，影响通信的正常进行。
发明内容
为了克服现有超5类数字通信电缆的不足，本实用新型提供一种耐寒型超5类数字通信实芯聚烯烃绝缘水平对绞电缆，可以增强电缆的抗拉伸抗弯曲性能和耐寒性能。
本实用新型提供的一种耐寒型超5类数字通信实芯聚烯烃绝缘水平对绞电缆，包括缆芯及外护套，缆芯内具有数个导线对绞组，在缆芯与外护套之间设有内护套。
为了进一步增强本实用新型的耐寒性能，在制作外护套的聚烯烃护套料中添加增塑剂、稳定剂、耐寒剂等助剂。
本实用新型的有益效果是：由于电缆采用内护套和外护套的双护套结构，明显减小电缆的拉伸应变，其抗拉伸抗弯曲性能增强。本实用新型的双护套结构以及采用耐寒的聚烯烃护套料制作外护套，使电缆的耐寒性能明显提高。因此，本实用新型即使在室外较寒冷的环境中使用也不易开裂受损。本实用新型不仅适应在室外使用，也可作为集散系统、自动化检测系统、计算机局域网机房中的数字传输电缆。
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、绝缘层，3、导线，4、撕裂绳，5、导线对绞组，6、缆芯，7、内护套，8、外护套。
具体实施方式
参照图1，在导体1外包覆绝缘层2制成导线3，将两根导线3绞合成导线对绞组5，然后将数个导线对绞组5与撕裂绳4一起绞合成缆芯6，再在缆芯6外包覆聚氯乙烯内护套7和添加有增塑剂、稳定剂、耐寒剂的聚烯烃外护套8，即制成本实用新型。
