The NEC requires a minimum spacing of 12 inches (305 mm) between busbars, but this can be reduced based on the busbar current and configuration. The IEC standard for busbar clearance plays a critical role in the design and safety of electrical panels and power distribution systems. And for general industrial control equipment, voltage range 301-600, shortest distance is shown as 1/2" with this same value being shown through oil or air over surface. Between live parts of opposite polarity, 251-600V, Through air gap is 1", Over surface is 2".

If you can place bare conductors 1/2" apart and meet the test requirements for 15kV equipment, that is fine. And before you conclude that I'm being ridiculous, remember that we do this every day in vacuum interrupters.

To resolve this problem, a means of shock-absorption must be fitted to the tube that opposes and dissipates the vibration, taking into account the tube's natural resonance frequency. In vibration-prone electrical systems, rigid copper busbars alone are often not enough. Motors start and stop, compressors ramp up, generators vibrate on their skids, and busduct runs move with building expansion. Compact busbar systems provide efficient energy transmission in confined spaces, while corrosion-resistant cable trays enable organised and accessible cable. But this cheap method is not satisfactory as the cable subjected to the vibrations may come out of the tube if the end caps are not properly tightened or welded then could be loose, crea 00 CET FCA 2017-01-11 00:00:00 CET SDAMPER DOC.
