Cross Section Of A Wire
The cross section refers to the area of each wire of a cable and its size depends on several factors.
Cross section of a wire. D single wire diameter mm in. Wire cross sectional area calculations 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. On the one hand there are the electrical data of the connected machine and structural conditions such as cable length and installation type on the other.
A cross section area mm 2 in 2 d diameter mm in cross section area of bunched wire. A d 2 π 4 0 7854 d 2. The cross section area of bunched wires can be calculated as.
The cross section area of a round single wire can be calculated as. A n d 2 π 4 0 7854 n d 2. The area of that cross section is the well known a pi r which is colloquially pronounced as pie are squared.
Most wire is made with a circular cross section of some particular radius and diameter.
