I don't know what type of cable it is but if you get some Belden or Canare cable from the same place, you've got yourself the makings for some great sounding and very reliable instrument cable.
Hint: for great sounding super durable/indestructible cable, use microphone cable like the Canare Star-Quad. It has four separate stranded cables running down the core with shielding around it. Use all four soldered together for the signal. Use the shielding to carry the ground. I've made a few of these that have been on the road and are over ten years old and still work perfectly.
