# A question about wire area

For some reason I need a flexible wire whose cross-section is equilateral triangle with the length of one side is 2mm.

I couldn't find any wire or even material in the market in such shape.

So Im planning to find the closest possible round wire option.

If I would use a triangular cross section's area would be:

sqrt(3)/4 * d^2 where d is the edge length

for d = 2mm

Are becomes 1.732mm^2

So I need to find a cable with around this area.

From the tables I could closest find 15AWG which corresponds 1.6502mm^2

Is my way of thinking correct?

In wire sizing AWG is measure for the entire wire together with its coat or for the copper part only?

• why triangular? – Andy Mar 14 '18 at 13:55
• AWG measures the size of the conductor (the copper part). – Pete Becker Mar 14 '18 at 13:58
• As soon as you bend a wire with a triangular cross section you create a sharp edge that will try and cut its way through the insulation. I'm not surprised you can't find any. – Finbarr Mar 14 '18 at 16:02
• The suspense is killing me! What is the reason you need this? It feels *extremely unlikely you actually need that! – Marcus Müller Mar 14 '18 at 20:20
