Another application for stranded wire is in high frequency moderate to high
current applications. The negative impact of skin-effect is less in stranded
wire (more skin).

John,,

Your initial post stated that: "This cable has 36 strands, measuring 1.5
mils per strand."

I took that to mean that the diameter of each individual strand was 0.00150
inches.

Based on the tables, a 46 gauge wire is 1.57 mils (0.00157 inches) diameter,
and a 44 gauge wire is 2.0 mils (0.00200 inches) diameter.

My gut feeling is that if you measure a single strand again it will turn out
to be 1.57 mils (as opposed to your original statement of 1.5 mils), which
would mean that the individual strands making up your wire are each 46
gauge.

Is it possible that there is an error in your initial post, and are you
meaning to say that your measurement was 0.15 mm diameter, as opposed to 1.5
mils diameter?

Is it possible that you are confusing "area" with "diameter"?

Where are you getting your numbers?

What is the total diameter of your wire (all 36 strands)?

What would you say that you think the approximate AWG of the wire is
(including all strands)?

It seems that whatever the actual gauge, with the large number of very fine
strands, you may have a wire that is intended to be very flexable. The "MIL"
folks do this kind of thing occasionally.

Is there per chance any marking on the wire itself or possibly the spool?

JaMi
