The cable covering is calculated using the following formula: for spirals: U = π (D + d) and S = π (D + d) tan α F = U’ Z / U = n d Z / [π (D + d) sin α] β = F × 100 (%) for braids: U = π (D + 2d) and S = π (D + 2d) tan α For braids, the filling factor F and coverage β, taking into account both braiding directions and a symmetrical braiding pattern are: F = (U’/ U) (Z / 2) = {n d / [π (D + 2d) sin α]} (Z / 2)
and
β = F (2 − F) × 100 (%) where: S = lay length of screen in mm D = diameter under screen in mm (for cables with two or
