Abstract
A tubing apparatus includes corrugated tubing including convolutions of peaks and valleys in the body of the tubing; an electrically conductive or semi-conductive, polymer jacket disposed along an exterior length of the corrugated tubing; wherein the jacket provides protection to the inner corrugated tubing from damage resulting from electrical arcing at levels ranging from at least 9 coulombs at a waveform of 10 microseconds×1000 microseconds.
