The percentage of coverage that a wire braid contributes is a function of the diameters of the wire braid and the underlying structure, the number of carriers (group of wire ends), the number of individual wires in each carrier and the picks per inch (the points of crossing-of the carriers). An illustration of wire braid is shown in above figure formulae are applicable for computation of percentage coverage of braid: Percent Coverage = (2F - F2) x 100Where: F = NPd/Sin A A = Tan-1-1 2p (D+2d) (P/C) And: C = Number of carriers (groups of ends) N = Number of ends (strands) per carrier P = Picks per inch (carrier crossing points) d = Diameter of individual wire strand (inch) D = Diameter of structure under the braid (inch)
