What model and specification of cable should be used for the power cables that supply power externally to the instruments (220VAC, 24VDC)?
Thread Content
For power cables used in instruments (220VAC, 24VDC), should VV 2 X 1.5 or BVV 2 X 1.5 be chosen?
We usually use ZR-K V V-0.5 2 X 1.5
Copper-core insulated circular cables BVV, with polyvinyl chloride insulation VV, are both suitable as power supply cables.
Generally, both VV and BVV are acceptable; the requirements for power cables are not that high. On the second floor, control cables can be used directly as power cables!
Selection should be made in accordance with relevant standards; in principle, the power supply for instruments should be housed in conduits. It is difficult to use ordinary VV cables for this purpose, as they are prone to damage and other issues
Please advise; it is specified in that standard. Thank you first!
We use shielded twisted pair for our engineering work, haha. Isn’t it a bit of a waste?

It is recommended to use KVVR soft-core cables, as they can be moved slightly, which is great.
VV, BVV, KVV, etc., should all work; we generally use (R)VV3*1.5.
