1000 Kcmil Copper Wire Diameter
Second multiply the diameter by 1000 to find the area in kcmil or by 3.
1000 kcmil copper wire diameter. Suitable for use in electrical grounding systems including counterpoise grounding and on insulators for overhead transmission and distribution applications. Stranded bare copper bare or tinned soft annealed medium hard or hard drawn stranded bare copper. Wire cross sectional area calculations. 61 cross section area mm2.
Stranded conductors offer greater flexibility than solid 250 kcmil 1 000 kcmil. 1000 kcmil cu 220 nl epr sim pvc jkt 15kv ct. First find the diameter of the wire. Additionally it s in industrial and commercial installations power circuits in generating plants where a line to ground fault current are within shield capabilities.
1000 mcm number of strands. The n gauge wire s cross sercional area a n in kilo circular mils kcmil is equal to 1000 times the square wire diameter d in inches in. Color coded polyvinyl chloride pvc heat and moisture resistant flame retardant compound per ul 1063 and ul 8. We first convert from kcmil to circular mil.
Awg 4 3125 ln mm2 17 16 approx interpolated awg 4 3125 ln inch2 10 74 approx interpolated logical awg numbers are based on continuing the series in a logarithmic relationship to the cross sectional area of the wire. Mil means 1 1000 inch. The formula to find the cross sectional area of the wire in square millimeters is. The following table of wire sizes does not show any sizes bigger than 4 0 gauge because solid copper wire becomes impractical to handle at those sizes.
Steps to find the cross sectional area. Area mm 2 π 4 diameter 2. Kcmil circular mils x 1000. 1 kcmil 1 mcm 1000 cmil 506 7 10 3 mm 2.
Solid uncoated copper conductors per astm b3 stranded uncoated copper conductors per astm b3 astm b787 and astm b8 insulation. Stranded wire construction is favored instead. Use the formula above to calculate the width if the awg is known. A n kcmil 1000 d n 2 0 025 in 2 92 36 n 19 5.
When large diameter wire sizes such as the widely used 250 kcmil and 350 kcmil wires are specified in kcmil the wire s diameter can be easily determined with the following formula. Circular mil means the area of a circle 1 1000 inch in diameter.
