Landing 15KV AL CN cable on live front transformer

[electrofelon]

I have to terminate the cable on a pole transformer which has the typical bronze eye bolt connecters on top of the bushings. After the termination kit, should I land the #2 AL conductor right on the transformer or should I transition to copper wire first? There is not a cutout or anything, cable goes directly to transformer primary. Typically I see POCOS tail off the transformer with copper and then splice to aluminum for the low voltage side, but I havnt been able to see an example of the HV side. These transformers will be in an enclosure and not out in the weather.

I'd guess the bronze connector isn't rated for aluminum conductors so you need to find a way to transition to copper.

It's hard to dig up the information on the transformer lugs, and probably not worth the time. I agree just an inline splice to a piece of CU is best bet

Solid or stranded #2?
Usually see these or a lug on the end of stress cones. Homac pin terminal, gives a tin plated copper pin. Termination kit seals on the connector body keeping moisture from entering the cable through the conductor strands.
