The 8866 002100 is a 100ft 1-conductor Hook-up/Lead Wire with 18AWG (16 x 30) tinned copper conductor, conductive polyethylene (Korona-Guard) over inner conductor provides uniform distribution of voltage stresses, polyethylene insulation and red PVC jacket. Uses uni-strand tinned copper conductors, in this type of construction, the bare copper wires are stranded, then tinned to coat the strands and also to fill in the interstices between the strands. This allows for easier wire stripping with no re-twisting operation.
