(OP)
Does anyone know of another manufacturer of HV, 38 kV+ vacuum switches for capacitor bank switching, other than Joslyn?

RE: Vacuum Switches

ABB makes them for up to 43 kV grounded.  Cooper switches only go to 34.5 kV, I think.

DCP, thank you, and Cooper only goes to 27 kV.

about BIL, at 35 kV, whether to use 150 vs 200 BIL. where is the best place (non IEEE member) to find/prove which value you choose for the application of an vacuum switch substation application?
