Constrained layer damping tape on toroidal transformer?


Is it safe for me to apply constrained layer damping tape (aluminum core) directly to the exterior plastic wrap of a toroidal transformer?  Are the wire wrappings around the core insulated?

Thanks for the tip, Ralph! I think I’ll mount my transformer with a non-magnetic stainless bolt.

I would like to know why you say not to use a stainless nut, though. I build a lot of stainless parts for race cars and for food and beverage and try not to use stainless nuts on stainless bolts due to galling, but that’s only if they have a decent amount of torque applied to them. For lightly tightened things like a transformer, though, there usually isn’t a galling problem. So, why not use a stainless nut? You could always use a little bit of anti-seize if you’re worried about galling.
Ironically, perhaps, mu metal, a high permeability low frequency alloy commonly used to shield/absorb magnetic fields of transformers, including toroidal transformers, contains ferrous metal. Not sure I would pay too much attn to a ferrous nut. Or ferrous bolt for that matter. Besides as I already commented, bolts on transformers is a rather dumb idea, with the exception of shipping the component, quite unnnecesasry and bad for the sound. 
Sorry, but not bolting a high voltage component to the chassis is idiotic. Plus, if you isolate the bolt and transformer correctly, it will be like it’s not bolted in at all until you actually need to count on the bolt, like if you pick the component up and forgot you didn’t bolt it in, someone bumps it, etc.

Why not leave the transformer outside of the chassis and just run the wires into it? I mean, you might as well go all the way if you’re going to be dangerous about it.

Anti-galling compound should work fine...  I'm just nervous about it perishing and being a problem years down the road.

Just for fun, if you have one of those lazer temperature sensing gadgets, its easy enough to see that a ferrous bolt runs considerably hotter than the transformer itself. Its also easy to see that the latter runs cooler once the bolt is replaced.
