Transformer Load Break and Arrester

[prajwal2341995]

Hello,

I am working on a project where I am struggling with this issue below. Can please advise on this as its really important.

We have procured a transformer with 35kV 600Amp dead break bushing which is setting on a PAD. Our interconnection voltage is 12.47kV JCP&L.
The MV cable we are using is (3) #2 AWG AL (MV-105), 15kV CLASS, EPR 133% INSULATED 3Ø CONDUCTORS WITH 1/3 CONCENTRIC NEUTRAL.
The surge arrester rating is 15kV 7.65 MCOV/ or 35kV 8.4MCOV 200A arrester (this one preferred) (in surge arrester spec sheet page 2 highlighted in yellow).

I have reached to every vendor to find out how we can make this connection of surge arrester rating to transformer work.
My thought is in the PDF attached but I have recieved this response from my vendor that "The Cooper is for a large interface and the Elastimold is a small interface".

Can someone please advise me on this? Which adapter or extender I should use with 35kV 8.4MCOV surge arrester?
If not, is there any alternative?

What I'm not clear on is do you have a bushing available for the arrester, or do you need to make one with something like loop feed/feed thru insert?

Bushings are already coming with transformer. Need some way to connect 15kv 600A/200A, 7.65/8.4MCOV arrester to 35 kV 600A transformer bushing.

I am not clear on the vendor's comment about the large and small interface. If that adapter reduces you to a 200 amp interface and that's what your arrestor is, it seems like that is what you need. I must be missing something.

Maybe try getting in touch with someone in Eaton's separable connector department and cut out that middleman?
