It isn't. Perhaps it's time for me to post a series of actual 
measurements showing just how it really is (yet again). It is nothing 
like Litz - there is no insulation on the individual strands. If 
anybody doubts this, insert a foot of braid in your primary resonant 
circuit and check the temperature rise after a run.
