在系统信号的数据传输和自动化连接当中，计算机线缆作为通讯线缆的一种，起着非常重要的作用，它是由一对以上的绝缘线缆组成，数个绝缘导体或体绞线的线缆芯和维护线缆芯免遭湿气和设备破坏的外护线套构成。随着科学信息技术的发展，使得计算机电缆得到了更加广泛的应用。

计算机电缆主要用于以电子计算机为主的自动化控制系统，以及检测用的仪器仪表当中，例如电力、石化、冶金等行业，额定电压500伏以下的对于防干扰性能需求比较高的自动化连接使用。根据使用的不同场合，计算机电缆屏蔽层通常分别采用分屏蔽、总屏蔽、次屏蔽加一般屏蔽等，通常情况下根据用户的不同需求和具体使用环境，总屏蔽往往采用由金属丝编织和金属带缠绕的两层复合屏蔽方式。
