For 220V control circuits, unshielded cables can be of any length without causing interference that would affect the system’s operation. Due to poor communication between the design firm, equipment manufacturers, and the client, a batch of control cables was ordered as unshielded. In the case of ABB control systems with 220V input, as long as the cables are not too long, the interference caused by their length will not affect the operation of the equipment. Are there anyone with experience in this area?

Be installed separately at sufficient intervals and apart from the power supply

Should it also be separated from other control cables and laid separately?
