In a common conduit, 10KV cables, 220/380V cables, as well as control/communication cables need to be installed. How should it be arranged?

A common conduit is required to carry 10KV cables, 220/380V cables, and communication cables. How should it be arranged? In this case, are the three types of cables arranged in high, medium, and low categories, or must the 10KV cables be placed in cable trenches or buried directly? Please ask experienced sea travelers to help analyze it.
It’s not one cable tray; 10KV, 380V, and 24V each have their own separate cable trays, arranged at high, medium, and low levels with a spacing of 50cm. If it were you, how would you arrange it?
If it were me, 24V at the top and 380V in the middle.
I place the cable trays for the large bridges at the bottom, separating high-voltage and low-voltage cables with a distance of over 1 meter between them, and arranging them at different heights
10KV is at the top, 380KV is in the middle, and 24V is at the bottom. Cable cooling is very important; if 24V is at the top, it will basically be continuously heated by the heat from the cables below
There are installation specifications for this; it is recommended to consult the relevant guidelines and determine the approach based on the actual circumstances
The 10KV and 380V cable trays are located on the upper level, separated from each other, while the 24V low-voltage cable tray is placed on the lower level, with a distance of over 1 meter between the two levels.
