National standard wire diameter table and calculation method National standard wire diameter table

 Wire (square mm) Conductor diameter (mm) 1.5 1.38 2.5 1.78 4 2.25 6 2.76 10 1.33×7 16 1.70×7 25 2.10×7 35 2.50×7 50 1.78×19 70 2.10×19 95 2.50×19

Note: The above conductor diameter refers to BV plastic copper wire and BLV plastic aluminum wire

Conversion method: know the square of the wire, calculate the radius of the wire with the formula for calculating the area of the circle: wire square number (square millimeter) = pi (3.14) x wire radius (mm) square

Knowing the square of the wire, the same is true for calculating the wire diameter. For example, the wire diameter of a 2.5 square wire is: 2.5 ÷ 3.14 = 0.8, and the square root is 0.9 mm, so the wire diameter of a 2.5 square wire is: 2×0.9 mm = 1.8 Mm.

Knowing the diameter of the wire, the square of the wire is also calculated by the formula for finding the area of a circle: the square of the wire = the circumference of the circle (3.14) × the square of the wire diameter/4

The cable size is also nominally squared, and the multi-stranded wire is the sum of the cross-sectional area of each wire. The calculation formula of the cable cross-sectional area: 0.7854 × the square of the wire radius (mm) × the number of strands such as 48 strands (each wire with a radius of 0.2 mm) 1.5 square wire: 0.785 × (0.2 × 0.2) × 48 = 1.5 square
