Seeking help with cable selection for the DCS cabinet room
Thread Content
I have been working on this area recently. I’m not sure how to select the cables for use in DCS cabinet rooms. For example: power cables, signal cables, etc. Have you done this before? Or are there any regulations, standards, or something of that kind in this regard? Thank you
The power supply is calculated based on the power requirement, and thicker cables should be chosen as much as possible; in signal cable cabinets, the standard gauge is usually 0.75mm2.
It is calculated based on the system’s points and signal type
GB-50217 covers this aspect; search for it by yourself. The signal lines should be shielded wires, while the power lines can use ordinary multi-strand flexible wires. The size of the cable depends on the power; there’s a rough guideline for this, and you can search for it – I won’t write it down here.
Aren’t there design drawings? It’s on the drawing.
For on-site construction, KVVP 2*1.5mm2 solid wire or KVVRP 2*1.5mm2 flexible wire is generally used; the cross-sectional area of the wire should be at least 1mm2, as smaller cross-sectional areas make the wire more prone to breaking
