Can instrument cables be placed on an electrical tray?
Thread Content
I need help. As shown in the diagram below, a section should be set aside on the right side of the cable tray; the power cables for the motor should be placed in the larger area on the left side (the motor has a rated voltage of 380V, power of 110kW, and a current rating of 200A). The cables for the instruments should be placed in the smaller area on the right side (these cables are used for temperature probes and vibration sensors). I’m not sure if this approach is feasible. Is it okay if it’s not an analog signal? Are there any relevant standards? First, thank you all.
Temperature and vibration are prone to interference; your power cable carries a high current, so it’s not suitable.
Refer to standard HG/T20512-2014, P294
It’s best not to do this, otherwise it will cause a lot of trouble later on.
No, high-voltage and low-voltage circuits must be separated, as well as power supply and signals. Go and check the specifications yourself.
No, high-voltage and low-voltage circuits must be separated, as well as intrinsically safe and non-intrinsically safe circuits
There should be enough distance between the two to prevent interference
