Conductor Spacing
Conductor Spacing
(OP)
WHat is the minumim spacing requirement between bare conductors (lugs) for 15 kV class equipment if you want to maintain 90 kV or better BIL? Is there some document that would summarize the necessary spacings for different voltage/BIL levels?
Thanks,
Dave

RE: Conductor Spacing
Manufacturer's can use smaller distances if they test the equipment to prove no flash over.

The Minimum phase-to-earth and phase-to-phase [mm] is stated as follows:
BIL[KV] INDOOR OUTDOOR
75 120 160
95 160 160

Good deal. Thanks for your help.
