I just don't know where there's an appropriate group for this so thought I'd ask here.
I have a transformer (out of a fairly old SOLA CVT) whose 115V input leads have become fragile right at the point where they enter the windings. It is good enough to get a wire spliced onto it but I would like to stabilize the point where it enters the transformer.
This transformer was inside of a metal housing and poured with a generous layer of tar to stabilize everything - including the laminations as those can be noisy. While tar would probably work, I'd rather use something else and only at the point where these two wires enter the core to hopefully prevent further breakage after the splice is made. I'm thinking of making a small form at the end of the core around the wires and pour a potting compound of sorts in the form.
My first thoughts would be something akin to silicone sealant but, as I understand it, that stuff is not kind to wiring. Roofing tar might work if it sets up firmly enough but, again, would like to steer clear of more tar. Is there something out there that would work well for this?
Feel free to respond directly to me.
