It need not necessarily have to be a circle.Ĭommercially available wire (cable) size as cross sectional area:Ġ.75 mm 2, 1.5 mm 2, 2.5 mm 2, 4 mm 2, 6 mm 2, 10 mm 2, 16 mm 2.Ĭalculation of the cross section A, entering the diameter d = 2 r:Ĭalculation of the diameter d = 2 r, entering the cross section A: The cross section or the cross sectional area is the area of such a cut. Litz wire (stranded wire) consisting of many thin wires need a 14 % larger diameter compared to a solid wire. Or centimeters, when you take for the area the square of that measure. The 'unit' is usually millimeters but it can also be inches, feet, yards, meters (metres), You will see the program but the function will not work. The used browser does not support JavaScript. (Three-phase (DS) / AC (WS))Ģ) Fuse - Upstream backup = Maximum permissible current (Amp)ģ) On schedule to be transmitted power (kVA)ĥ) Permissible voltage drop (% of the rated voltage)Ħ) Line material. The required cross-section of an electrical line depends on the following factors:ġ) Rated voltage. Resistance varies inversely with the cross-sectional area of a wire. Why is the diameter value greater than the area value? Because that's not the same. Round electric cable, Cliphouse 1 0 6 Vm I486 7z conductor, wire, cord, string, wiring, and ropeĬross section is just a two-dimensional view of a slice through an object.Īn often asked question: How can you convert the diameter of a round wire d = 2 × r to theĬircle cross section surface or the cross-section area A (slice plane) to the cable diameter d ?
Cable diameter to circle cross-sectional area and vice versa.
