This is brake wire.
Brake wire
SJ cord USES the SAME jacket as your trailers power cord and even the trailer to vehicle cable. My trailer is parked beside a busy road and GETS a lot of winter cold along with the salt spray from the road. Trailer is plugged in year round and I have not seen any deterioration of that cord and it is the original cord and at 31 years of age I don't think anyone is going to have a problem using SJ..
That SJ jacket will easily outlast the trailer.
I don't buy into the idea that a wire sold as "RV" wire or "brake wire" is going to last longer. You brake wires ARE out of the sun so UV exposure is not an issue.
