I want to know whether I can use this d-link 3+1 CCTV cable for powering an led strip which runs at 12 volts 1 amp. The led strip is approximately 12 meters away from the smps power adapter. I checked the datasheet of the cable for power ratings on the 3 multi-strand copper wires but they're not given. All that is provided is that there are 14 strands per wire and they're 0.1mm diameter each I think. No cross sectional area or resistance is stated.
No cross sectional area or resistance is stated.
But, you can work that out... a 0.1 mm diameter wire has a CSA (cross sectional area) of 0.007854 mm² and, given that there are 14 of them, that's a net CSA of 0.11 mm².
Then, google an AWG table and see which wire has the closest net CSA. Here's one: -
It looks somewhere between AWG 27 and AWG 26. So, google what the current carrying capacity is of these types of wire: -
It looks like 26 AWG is only really recommended for a maximum current of 361 mA so, you might be out of luck.

I think probably not.
