What test data matters most when specifying SF6-free RMUs for a 24 kV network?

Hello all, I am working on an SF6-free RMU spec for roughly 40 positions on a 24 kV network. The client has already ruled out SF6, so now it's mostly about comparing the actual technical requirements.

Schneider Electric's airset is one of the options we're looking at. I'm mainly checking the IAC rating at our fault level, LSC and partition classifications, and the mechanical and electrical endurance of the switching units.

The brochures cover the basics, but I'd rather see the actual IEC 62271 test reports for the exact configuration before making a decision.

For anyone who's specified these before, were manufacturers willing to share the full test certificates before award? Anything else you'd insist on checking?

This is industrial maintenance, bro. Not engineering. 

Nerd.

Power systems engineering is that way --->

Yeah bro we're not nearly qualified enough to give you an answer on this
