Cross section of wire

WebA wire is a flexible strand of metal . Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number or cross-sectional area . Wires are used to bear mechanical loads, often in the form of wire rope. WebThe optimal wire cross-section for lighting is 1.5 mm2 for the line, 4-6 mm2 at the input. The ratio of the cable diameter to its cross-sectional area. Determining the cross …
