Does anyone know what type of tape that is used on a transformer core to hold the nonexistent paper on the core? The tape they use to tape the seams?

I opened the paper it was right next to the end and there is one tiny little dot on one wrap of wire. What I found out happened was when this transformer got its bushing hit by a fork lift it shifted the core and it was sitting on the tank and it burned a small dot through the paper and was grounding onto the can. A good couple of coats of electrical varnish should fix it right up... man I’m so happy good end to a Friday!
