interference on 24VDC signal

Dear,

I was looking at some specification documents it says that distance between cable trays carrying 3.3kv and cable trays carrying 24VDC should be at least 140cm.

However, I have distance limitation of 0.8meter total and I am using armored cables. is this distance still applies? thank you and any though is really appreciated.

To avoid the effects of coupling or loop area, keep the same distance between the 3.3kV Cable and 24 V DC.
The distance should be at least 5 cm in the case of a horizontal circulation and are 30 cm in the vertical circulation.
