为了叙述方便,我们把Ⅰ、Ⅱ类信号电缆统称为信号电缆,把Ⅲ、Ⅳ类信号电缆和现场电源电缆统称为电源电缆。在有条件的场合,信号电缆和电源电缆应采用不同走线槽走线,在进入DCS机房(或机柜)时,也应尽可能相互远离。当这二种电缆无法满足分开走线要求时,它们必须都采用屏蔽电缆(或屏蔽双绞电缆),且满足以下要求:
1、如果信号电缆和电源电缆之间的间距小于15cm时,必须在信号电缆和电源电缆之间设置屏蔽用的金属隔板,并将隔板接地。详细参见图1(略)。
2、当信号电缆和电源电缆垂直方向或水平方向分离安装时,信号电缆和电源电缆之间的间距应大于15cm.
对于某些干扰特别大的应用场合,如电源电缆上挂接电压为220V AC,电流在10A以上感性负载,而且电源电缆不带屏蔽层时,那么要求它与信号电缆的垂直方向间隔距离必须在60cm以上。
3、在两组电缆垂直相交时,若电源电缆不带屏蔽层,最好用厚度在1.6mm以上的铁板覆盖交叉部分。
