The armored cable shall not be less than 12 times the outer diameter of the cable.
电缆的屏蔽要求是根据不同场合分别采用:对绞组合屏蔽、对绞组成电缆的总屏蔽、对绞组合屏蔽后总屏蔽等方法。
屏蔽材料有圆铜线,铜带、铝带/塑料复合带三种。
屏蔽对与屏蔽对具有较好的绝缘性能,电缆在使用中若屏蔽对屏蔽对之间出现电位差时,不会影响信号的传输质量。
每个电缆盘外侧应标明:a、制造厂名称或商标b、电缆型号及规格c、长度md、制造日期:年月e、标准编号f、毛重kg:g、表示电缆盘正确旋转方向的符号3、运输和保管a、线盘不允许平放b、运输中严禁从高处仍下装有电缆的电缆盘,严禁机械损失电缆。

型号中最后一个B(如果有的话),代表该电线为扁线——如果没有最后一个B,则代表该电线为圆线。
扁线通常只有单芯,而圆线则更容易做成多芯线——同一个护套内有多根绝缘电线。
家装型号推荐家装使用电线,一般分为明装和暗装两种,下面我分开来说:暗装——建议使用BV线或BVR线,两种电线用起来区别不大,BV线的价格会更低一些,着重推荐。
BVV线和BVVR线也可以用于暗装,一来价格高,而来换线时必须一下换多根,很不方便,不推荐使用(使用护套线暗装,也需要穿管)。

人并没有变,仍然主要是用眼睛和手。
人机界面的进步,只能体现在能使人看到的内容更直观、更丰富、更生动和更准确上。
在理解人手的动作方面更准确、更快捷而已。
电子技术在可视技术方面的发展,令人眼花缭乱。
它的出现和日新月异的发展,为我们眼睛接收信息能力的扩展提供了几乎无限的可能。
它被立即应用到人机界面中,几乎也成了不可或缺的主角。
我们已经对各种仪表、按钮、指示灯、开关、仪表盘、控制箱,甚至遥控器之类十分熟悉了,只是没有把它当成是人机界面而已。
