Today I bought this cable in SLM LHS (3rd story).
It is Belden 83337.
Thou obsolete but a bit more left in LHS.
This cable cost about $18 per meter w/o gst.
It is bery for expensive for pro audio, I guess.
But it is one of good silver-coated copper 3 core cable competitor.
It got 90% shield and max 11 amp.
21 ohm/km.
Good for sign and power supply(consumer ones).
Becos 90% shields, it might not be good for mics.
Anyway, this cable is more rigid than your mic/instrument/patch cable.
Use it when you have fixed wiring and not much bending.
I have bought the same cable much later, and like it lot.
Most importantly, it is silver-coated copper.
Generally, it is got more high and your system will not sound "sluggish".
But a bad design of this type will sound harsh.
One thing about silver-coat copper is that even silver oxidised, it is still a conductor.
While 100% OFC, not matter no good, once cut and terminated.
The 100% is gone.
There is the spec(if you really care):

Update wire is with an E in the end.
