38 KV OIL Circuit Breakers

[jcp1187]

HI every one,
I need to perform PM on some old Oil CB's but I can not find anybody to provide spare parts on this CB made in Japan by Enoue Electric Co. 27 years ago.
What is your recomendation in terms of preparation in case
some parts (electrical and mechanical)are needed to be replaced?
I'm considering to upgrade this Power plant based on the problems to find parts. What would be your recomendation
between Vacuum and SF6 circuit breakers?

Sincerely,

jcp1187

As far as this particular breaker, I have no idea.

Regarding replacement breaker, 38 kV is at the upper limit of vacuum interrupter capability, or at least the last time I checked it was.

If vacuum is available, it will make things simpler compared to SF6.
