Litz wire - a type of winding wire used for coils and windings operating at such frequencies at which solid wire cannot be used due to skin effect.

Cost

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
