How is the cross-sectional area of copper braided wire calculated
When ordering copper braided wire, customers often ask you how to calculate the cross-sectional area of the copper braided wire. Is it width * thickness = cross-section? The following is a detailed answer to the problem of calculating the cross section. For example, taking 25mm2 copper braided wire as an example, the conventional specification is 48 * 30 * 1 / 0.15. 48 refers to the number of mounds of the machine, that is, how many strands of copper wire are composed of. 30 refers to 30 copper wires per share, and 1 refers to single layer. Sometimes we can see numbers such as 2 and 3, which means double layer and three layers. 0.15 after the slash refers to the single wire diameter of copper wire, which is 0.15mm. Area calculation formula of circle: Pi × radius × Radius, so the calculation formula of copper braided wire is how many copper wires * PI × radius × Radius, i.e. 1440 * 0.075 * 0.075 * 3.14 = 25.434 square meters, nominal 25 square meters.
