I use thick clear tubing, like aquarium tubing for all the cords. I slice it open carefully with a x-acto knife, then put it on. It’s been enough of a deterrent. I also use this super super thick foam stuff, I have no idea what its for but it works too. Yours might eat through that though.
I’ve heard of nic cube panels for wall trims.

Something that might be worth looking into is Clovers pellet and hay intake, Samson was a diggy, chewing monster until I cut down her pellets and supplemented with larger more varied salads, she eats a TON more hay now which I guess fills the urge to chew? I don’t know, I didn’t believe it until I saw it, really.

Hopefully the aquarium tubing will work! I know that has worked well for some too.  

 I’d say try ivory soap or the apple bitter GEL/CREAM on the tubing as well (my bunny Jack actually liked the apple bitter sprays, but he did not like the gel — maybe it lingered in his mouth or something) — however, don’t know if that would work with your hard core chewer.   It sounds like you have to completely block access to the outlet and then run the wire along an area that you can block.  You maybe be able to block it with nic cube panels or a mesh wire type of screen.  You can get the mesh wire screening at home depot or some supply store. 

I think in addition to blocking off wires-you should step up what she has that she *can* chew on. Hardwood chews, sissel balls, cardboard boxes, more hay, etc -sounds like you’ve got a real chewer there and maybe if you provide lots of good stuff to chew that may help.

I use NIC grids for all bunny proofing – instead of covering cords with tubing, I just block off access to the cords all together.
