Wire, Cable & Conductor Manufacturing worked example

Shield Coverage at 98% braiding and serving transfer efficiency: a worked example

This scenario runs the shield coverage calculation on the strong side: 98% braiding and serving transfer efficiency, with every other input held at its documented default. Use it when shield coverage in wire, cable and conductor manufacturing needs a buy quantity for the next wire, cable and conductor manufacturing run and you do not want to short the line.

The inputs for this scenario

  • Cable length to be shielded: 500 units (unchanged)
  • Shield material used per unit length: 0.08 units (unchanged)
  • Braiding/serving transfer efficiency: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Required shield coverage = covered amount × use per unit ÷ transfer efficiency) to the inputs above produces each figure below.
  • At this operating point the engine returns 40.82 units for required quantity, the number this scenario is built around.
  • At this operating point the engine returns 40 units for theoretical amount.
  • At this operating point the engine returns 0.82 units for loss allowance.
  • At this operating point the engine returns 98 % for efficiency.

How this compares with the baseline

  • Against the tool's baseline example, where braiding and serving transfer efficiency sits at 85% and the headline result is 47.06 units, this scenario comes in 13.27% below the baseline at 40.82 units.
  • Use it when planning a shielding run or issuing shield material to a braider, once you know cable length, consumption per unit, and the machine's transfer efficiency. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
