My cockatiel (bird) likes to chew the AC zip cords. So lamps, etc are all in danger. I used Teflon pipe tape the heavier blue variety and wrapped where he had chewed. Then rolled up soft paper towels (Viva) and taped them over the exposed cords, wrapping all 'extra' cord around the base. He leaves the paper covered cords alone.
I wrapped the Kimber 8TC speaker cable up just in case..
The fine turntable wires are a dread to think if he bit one even once. Poof. So I have objects around the back of the arm to physically prevent him from reaching them.
