Typical example of Litz wire cost (as of 2011)1) are shown in the table below. All wires have an equivalent cross-sectiona area comparable to 1 strand of 10 AWG wire.
|Stranding||Relative cost factor||Frequency at which skin depth equals conductor radius|
|1 strand of 10 AWG wire||1.00||2.6 kHz|
|10 strands of 20 AWG wire||1.86||26.5 kHz|
|26 strands of 24 AWG wire||2.73||64.4 kHz|
|66 strands of 28 AWG wire||3.20||171 kHz|
|110 strands of 30 AWG wire||3.26||272 kHz|
|210 strands of 33 AWG wire||3.46||554 kHz|
