Description
本申请是名称为:一种钢带加强型电缆、申请日为:2016年11月11日、申请号为:201610995448.0的发明专利申请的分案申请。
技术领域
本发明涉及一种电缆,具体是一种钢带加强型电缆。
背景技术
电缆,定义1:由一根或多根相互绝缘的导体和外包绝缘保护层制成,将电力或信息从一处传输到另一处的导线。定义2:通常是由几根或几组导线(每组至少两根)绞合而成的类似绳索的电缆,每组导线之间相互绝缘,并常围绕着一根中心扭成,整个外面包有高度绝缘的覆盖层。电缆具有内通电,外绝缘的特征。电缆有电力电缆、控制电缆、补偿电缆、屏蔽电缆、高温电缆、计算机电缆、信号电缆、同轴电缆、耐火电缆、船用电缆、矿用电缆、铝合金电缆等等。它们都是由单股或多股导线和绝缘层组成,用来连接电路、电器等。
为了防止受到机械损伤,电力电缆在外层铠装保护层,形成铠装电缆。电缆加上铠装层的目的除了增强抗拉强度、抗压强度等机械保护延长使用寿命外,更主要的是通过屏蔽保护提高电缆抗干扰性能,还有可以防砸、压、挤破电缆外皮后损伤线芯导致短路。铠装电缆主要用于化工、冶金、机械制造、发电和科学试验等的温度测量、信号传输及特殊加热,现有电缆的不足在于:抗压强度较低,承受的外力不够大;屏蔽效果差,不能用于电磁干扰严重的场合;内层导线保护层简单,导致外侧保护层一旦破碎,就会影响到电缆的工作,这些问题都是急需要解决的。
