Preparing Litz Seaker Wire AKA Cobra SHF SP Cord

I have over 50' of Litz "Cobra" cable and not sure how to prepare it for speaker hookup. It is a intwinde cable copper and green strands and the green appears to be coated copper wire or else it would short out if it wasn't coated? Putting a meter on the copper end to the other copper end good reading. Meter from the green end to the other end and poor reading. I assume I have to get the green coating off? Any suggestions or am I missing something simple? Thank you
