為了敘述方便，我們把Ⅰ、Ⅱ類信號電纜統稱為信號電纜，把Ⅲ、Ⅳ類信號電纜和現場電源電纜統稱為電源電纜。在有條件的場合，信號電纜和電源電纜應采用不同走線槽走線，在進入DCS機房（或機柜）時，也應盡可能相互遠離。當這二種電纜無法滿足分開走線要求時，它們必須都采用屏蔽電纜（或屏蔽雙絞電纜），且滿足以下要求：
  1、如果信號電纜和電源電纜之間的間距小于15cm時，必須在信號電纜和電源電纜之間設置屏蔽用的金屬隔板，并將隔板接地。詳細參見圖1(略)。
  2、當信號電纜和電源電纜垂直方向或水平方向分離安裝時，信號電纜和電源電纜之間的間距應大于15cm.
  對于某些干擾特別大的應用場合，如電源電纜上掛接電壓為220V AC，電流在10A以上感性負載，而且電源電纜不帶屏蔽層時，那么要求它與信號電纜的垂直方向間隔距離必須在60cm以上。
  3、在兩組電纜垂直相交時，若電源電纜不帶屏蔽層，最好用厚度在1.6mm以上的鐵板覆蓋交叉部分。
