Description

一种轻质通信电缆用填充绳
技术领域
本发明涉及到电缆生产制造技术领域，尤其是一种轻质通信电缆用填充绳。
背景技术
目前，随着社会经济的发展，电线电缆用量迅速增长，电力电缆的基本结构由线芯(导体)、填充层、绝缘层、屏蔽层和外护套四部分组成。线芯是电力电缆的导电部分，用来输送电能，是电力电缆的主要部分。绝缘层是将线芯与大地以及不同相的线芯间在电气上彼此隔离，保证电能输送，是电力电缆结构中不可缺少的组成部分。15KV及以上的电力电缆一般都有导体屏蔽层和绝缘屏蔽层。电缆一般在线芯设置填充层保护，填充层的作用是能够提高电缆的韧性、抗拉伸性能，防火阻燃，保护电力电缆免受外界杂质和水分的侵入，以及防止外力直接损坏电力电缆。
填充层的作用在电缆的使用中显得尤为重要，现有技术中电力电缆填充层材料的保护作用往往不理想，综合性功能较差，需要改良。
发明内容
本发明的目的在于提供一种轻质通信电缆用填充绳，具有优异的阻燃性、耐腐蚀性和抗老化性，重量轻，柔韧性适中，可根据电缆线芯的不同结构来填充空隙，填充性和物理性能好，使用寿命长。
为实现上述目的，本发明提供如下技术方案：
