Actually, a data cable tray is a low voltage cable tray also. Data systems are accepted as low voltage systems. Ordinary two data cables do not form any magnetic disturbance to each other. So for an ordinary situation no vertical or horizantal distance required.
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
Electrical conductors
Voltage Grade of cables specifies the safe voltages which the insulation of the cable can withstand.

Below 24 volts: low voltage cables are like other cables but without so much insulation. They are made of copper and insulated with pvc, usually only one layer. They are most commonly used in cars.

Ribbon cables are mostly, but not always lower voltage signal carriers. Power cables are mostly larger and carry higher voltage to various parts tht need it.
A cable suspension bridge is a bridge hung from cables. These bridges has cables suspended between towers as well as vertical cables.

Transmission power cables are designed by current carrying capacity.

Why is use the triangle system in high voltage cables

No, staples are not required where cables are run horizontally through holes in framing members. When the cable changes direction from horizontal to vertical runs from the last hole a staple is required, no greater distance that 16 inches from the hole.
