AWG38/1500 HIGH FREQUENCY SILK COVERED LITZ WIRE SUPER THIN
ENAMELED COATED COPPER LITZ WIRE
Litz wire employs a stranded wire with individually insulated
conductors (forming abundle). Each thin conductor is less than a
skin-depth, so an individual strand does not suffer an appreciable
skin effect loss.The strands must be insulated from each
other—otherwise all the wires in the bundle would short together,
behave like a singlelarge wire, and still have skin effectproblems.
The electromagnetic effects that cause the skin effect would still
disrupt conduction. The weaving or twisting pattern of the wires in
the bundle is designed so that the individual strands are on the
outside of the bundle for a distance (where the EM field changes
are smaller and the strand sees low resistance), and are inside for
a distance (where the EM field changes are the strongest and the
resistance is higher). If each strand has a comparable impedance,
current is distributed equally among every strand within the cable.
This allows the interior of the litz wire to contribute to the
overall conductivityof the bundle.
