Wire, Cable & Conductor Manufacturing worked example

Cooling Trough Dwell at 12% dwell allowance for splices and speed ramps: a worked example

Push dwell allowance for splices and speed ramps up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when cooling trough dwell in wire, cable and conductor manufacturing needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Conductor length to cool through the trough: 120 units (unchanged)
  • Line speed through cooling trough: 12 units / hr (unchanged)
  • Dwell allowance for splices and speed ramps: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base cooling trough dwell time = required work รท processing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for adjusted run time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base run time.
  • At this operating point the engine returns 12 % for allowance applied.
  • At this operating point the engine returns 12 pieces / min for process rate.

How this compares with the baseline

  • Against the tool's baseline example, where dwell allowance for splices and speed ramps sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It divides the required run length by line speed to get base cooling time, then multiplies by an allowance factor to cover splice stops, speed ramps and trough loading. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
