Well, I was planning to upgrade all my machines to 128 EU/t (Medium Voltage) using Transformer Upgrades. But there's no such slot in the Canning Machine. The same happens with the Miner. I wanted to place MFEs above it, but I need to place LV-Transformers first.
I Searched the forum, I didn't find this suggestion anywhere.
