Specifications for laying signal control wires and 220V power lines
Thread Content
I have two questions: 1. In DCS systems, could someone provide the specifications regarding the spacing between signal wires and 200V power lines? 2. In structured cabling systems, in areas such as those containing network equipment cabinets, I was only able to find specifications for the spacing between 380V power lines and signal wires like network cables; I couldn’t find any standards regarding the spacing for 220V power lines. Is it because such standards haven’t been established yet? If anyone knows, please let me know
Does anyone know? Please tell me
Shielded cable, 2 meters in length reserved, with separate circuits for high-voltage and low-voltage signals
Well, I know that high-voltage and low-voltage circuits need to be separated. I’ve found the minimum spacing required for 380V high-voltage circuits, but I still haven’t come across any relevant standards for 220V circuits. Do you know anything about this?
Take a look at HG/T20512-2014 \"Design Code for Instrument Piping and Wiring\" – it contains relevant requirements.
