**what is the Braid Angle and Shield Coverage ?**The braid angle and the percent coverage of the braid shall be determined by the following formula:

Tan α = 2 π (D + 2d1) P/C

K = 100 (2F-F2)

Where:

K = percent coverage

F = EPd2/sin α

P = picks per inch of cable length

α = angle of braid with axis of cable

E = number of strands per carrier

d1 = diameter of one of the round shield strands or thickness of flattened strand

d2 = diameter of one of the round shield strands or width of flattened strands

D = diameter of cable under shield

D = Gb ( for cables with no fillers, cable factor from column G of Table 3-6)

D = Ab (for cables with fillers to round, use cable factor A of Table 3-6)

C = number of carriers

n = number of basic wires (see Table 3-6)

b = basic wire diameter
