Question What Cable is This? Wanna make interconnects.

Can someone tell me what kind of a cable this is? I wanted to make some Interconnect RCA Cables, I've read so many guides, some with 2 conductors, others 4, and as I asked the salesperson for a 4 conductor cable, they said they did not have any, instead he gave me this 5 conductor wire with 1 wire that looks like it's shielded from the rest. The others don't appear to be shielded at all. Now the guides tell me that I should solder 1 or 1 set of conductors to the cup or middle pin in the rca plug and another set to the ground including the shielding, but only on 1 end (usually the source), do same on the other end but cut off the shield entirely. This cable just confuses me, should I just group together the 4 unshielded conductors(blue, green, yellow, red) and make it the positive? Then use the White wire with the shield as the ground following the the ground/drain on one end rule?

Read up on shielding by this guy:
home page

For RF you always shield at both ends and 100% circle if possible...

It is a three phase cable with some type of signal cable. At least the colors correspond to old RYB standard.

Attaching a cable shield at one end is like using a chocolate fire guard

Maybe it's intended for a security camera. Shielded cable for video, two wires for power, two other wires to control a motor mount or illumination?

At the end of the day it does not look like cable suitable for making audio interconnects, use it for something else, and get some decent Beldon cable designed for the job.

Might be quicker and cheaper to just buy a ready-made interconnect cable. Not DIY, but unless you need a specific non-standard length there is not much point in making interconnects. No homemade cable will beat ordinary decent commercial cable, and merely soldering on the ends is hardly a creative activity.

Of course, if you want to modify the sound of your system you can make a cable which encourages RF ingress or is microphonic.

especially for RCA, its a completely weird recommendation, given RCA only has signal and ground, so its not like only connecting one end of the shield does anything at all except make the shield less effective.

in this case specifically, given the shield..isnt actually surrounding everything anyway… its pretty oddball for an RCA
