Distance between Power and control cables

We are laying 480 volts power cable on a cable tray and since there is no other spare cable tray that we can put our control cables, we will put them in the same tray. I just want to know what is the safe distance so that there will be no induction in the control cables(we are using 300mm cable trays). Is there an article or standard regarding safe distances of power and control cables?Thanks guys in advance:)
 
The answer will depend on whether the control (and even the power cables) are individual wires or twisted and/or shielded assemblies.
Also whether the control cables' signal is AC or DC and voltage or low or high current.

In addition the the insulation voltage rating is important.

True, although that will affect basic safety and code compliance rather than coupled noise.
The OP also mentioned inductive coupling even though capacitive coupling is more common unless "incidental" turns around ferrous metal are involved.

The power cable is 3 core(insulation rating 1KV) and control cables are 100VDC 7 core(with insulation rating of 600V)- power cable is shielded and armored while control cable is not. Is there a particular standard regarding this situation?
