【讨论】Marshalling box 中RTD电缆的处理
最近在接Heat Trace的热电偶的信号线，有个问题不明白，请行家指点。当电缆通过Connector进入Marshalling box后，西人（都是Journeyman）的做法是将电缆直接引到接线端子附近再将外层PVC去掉。有人说应该在Connector那里将PVC外层去掉。因为信号电缆有屏蔽薄膜，把PVC去掉后屏蔽薄膜很容易散。通行的做法是什么样？请行家指点。

Leave the conductor section where without the shield protection as short as possible! this rule is good for all the analog siganal or communiction cable (shield cable), and also you have to remember that you only need one end grounding! |
