Litz wire

Litz wire reduces AC losses
in conductors from skin
and proximity effects at
high frequencies to make
transformers and motors
more efficient. It consists of
individually insulated strands

woven or twisted in a specific
pattern so that each tends to
occupy all possible positions
in the cross section. This

equalizes
flux linkages
and
reactances
so that

current is evenly divided
among the strands. The
increased current-carrying
efficiency makes litz wire
popular in such applications as:

•

High-frequency inductors

and transformers

•

Motors

•

Relays

•

Inverters

•

Power supplies

•

Ultrasonic and sonar

equipment

•

Heat-induction equipment

•

High-twist applications,

up to 300 turns per foot

Kerrigan-Lewis litz wire is
available in a wide range of
configurations to meet specific
operating frequencies, voltages,
and current-carrying capacities.
Individual strands range from
50 to 16 AWG, with anywhere
from a few strands to thousands
in the wire. Besides traditional
round conductors, we also
offer space-saving square and

Specialty wire for

unique applications

Resistance wire

Kerrigan-Lewis resistance
wire achieves high-tolerance
resistive values with a
copper-nickel alloy. Standard
configurations are 55%
copper/45% nickel for a
resistance of 294 ohms per
circular mil-foot and 78%
copper/22% nickel for a
resistance of 180 ohms, with

others available. We offer the
wire in sizes from 40 AWG
to 25 AWG to meet specific
resistance and current-
carrying needs.
