Question 8: Are there any requirements for separation and segregation of various types of cables (i.e. Power, instrumentation, signal, telecommunications, etc.) in cable tray systems?
Home / Vertical spacing requirements between cable trays and pipes
In general, vertical spacing for cable trays should be 30 cm (12 in), measured from the bottom of the upper tray to the top of the lower tray. The spacing between trays, whether horizontal or vertical, depends on various factors like cable type, environment, and tray material. Proper installation can significantly reduce electromagnetic interference, prevent fire hazards, and improve overall efficiency. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. The cable tray is installed in parallel with the general process pipe (such as compressed air pipe) not less than 400 mm.

The cable tray is installed in parallel with the heat pipe. The heat pipe and the insulation layer are not less than 500 mm, and the heat insulation layer is not less than 1000 mm.
As per the NEC, the maximum allowable rung spacing is 9 inches (230 mm) when cable tray carries sin-gle-conductor cables of 1/0 to 4/0 AWG (American Wire Gauge) (Appendix I).
The cable should not be allowed to have a straight vertical run without the addition of a tension relieving section. This normally involves the cable having a short horizontal section (at least 1 metre) included
Subrule (6) requires that adequate working space be provided to provide access to the cable trays, to facilitate the installation and removal of conductors or cables,
Shortest and Straightest Path: To reduce cable loss and simplify maintenance, cable routes should be as short and straight as possible. Segregation of Power and

"Cables with copper conductors, regardless of their voltage class, installed in vertical runs should be supported in accordance with the following [attached a table].
Cable Support Distances Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. Section 522.8 (Other Mechanical Stresses (AJ))
In general, vertical spacing for cable trays should be 30 cm (12 in), measured from the bottom of the upper tray to the top of the lower tray. A minimum clearance of 23 cm (9 in) should be
A necessary space must be devoted to workers on the cable trays under the false floor (cable tray modifications, pulling and crimping cables) to avoid walking on it.
I could not find the clause in NEMA VE-2 that states the maximum support interval (spacing) for vertical straight cable tray runs. Can anyone refer me to any reference that may help
