That is normal. It is a semi-conductive layer. You'll find it both 
under the braid, and around the center conductors. It createds a 
voltage gradient to diminish stress on the hv insulation. Just unwind 
the semi-conductiing tape down to the orange insulation and give 
yourself enough stripped end so that it won't track.
