Cable Shielding Cost at 99% shield coverage of the cable od: a worked example

This scenario runs the cable shielding cost calculation on the strong side: 99% shield coverage of the cable od, with every other input held at its documented default. A cable designer specifying braid plus foil for EMI control uses it to price shielding material against coverage targets and grounding hardware.

The inputs for this scenario

  • Cable run length to be shielded: 800 ft (unchanged)
  • Braid or foil shield material cost: 1.35 $/ft (unchanged)
  • Shield coverage of the cable OD: 99 % (raised for this scenario; the documented default is 88)
  • Termination and grounding labor cost: 240 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total = cable length x shield material rate x shield coverage% + termination cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,309 $ for total cable shielding cost, the number this scenario is built around.
  • At this operating point the engine returns 1.64 $ / piece for cable shielding cost per unit.
  • At this operating point the engine returns 1,069 $ for variable cable shielding cost.
  • At this operating point the engine returns 240 $ for fixed cable shielding cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where shield coverage of the cable od sits at 88% and the headline result is 1,190 $, this scenario comes in 9.98% above the baseline at 1,309 $.
  • Use it while quoting a shielded cable assembly or comparing coverage options and their cost impact. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
