Cable manufacturers?


How many cable companies actually manufacture their own cable? 

Perhaps Mogami, Belden, Canare and a few others. I am willing to bet most cable companies do not manufacture their own cable, but simply buy cable, throw on some techflex or other custom jacketing, and do nice terminations. 

Anyone have any any actual Information?

"Mr. Teo, do you have a technical paper you could point me to about this whole atomic/molecular-level liquid conductor? I mean a real peer reviewed and published scientific paper. I have an advanced Engineering degree, I can handle it:) I always like to learn new things and I am hoping this is not like the infamous clever little clock or some brilliant pebbles that were peddled on Audiogon."

Whoa! What? Hey, Did I just detect a subtle bashing of the Clever Little Clock and Brilliant Pebbles? They aren’t no. 1 on Agon for nothing, ya know. Geez, they’re looking for peer reviewed scientific papers again? Must be the Skeptic Society working overtime. This is a hobby, not a NASA mission to Mars. Hel-loo! You always want to learn new things. I’m sure!

I like the spirit of OP's initial query.  Hopefully, the big guys are not junk-sourcing to china like so many audio electronic companies. Valid questions.
News flash!! - sourcing to China is a nothing burger. Sinophobia, plain and simple.
China can build anything at any level there is .
 USA has 10% of industrial capacity it had at start of WW II and has an economy based upon selling slips of paper aka Wall St .
