Introduction to 8 litz wire types and their application 

This is a very detailed Introduction to 8 litz wire types and their application based on Frequency and Gauge-Chart.tell us application and your devices operating frequency ,we will give recommendation accordingly

In this article,the litz wire types classification method is based on the “construction” of the cable.you can also classify based on different insulation /conductor materials

We will recommend based on different insulation accordingly

Type 2 Litz construction features bundles of twisted wire twisted together with optional outer insulation.
Outer insulation can be  textile yarn, insulating tape or extruded compounds

Conductor:Bundles of Type 1 Litz wire

Application:Similar to Type 1 litz,the smaller constructions of Litz type2  are typically used in high Q circuitry, such as toroidal coils and transformers

Type 3:

Round type 3 litz wire based on Individually insulated bundles
Round type 3 litz wire based on Individually insulated bundles

Round Type 3 Litz cable is featured with ” insulated bundles of twisted wire twisted together with optional outer insulation”.
Outer insulation can be textile yarn,insulating tape or extruded compounds.

Conductor:Individually insulated bundles,Bundles of Type 2 Litz wire

Application:Similar to Type 1 and type 2  litz,the smaller constructions of Litz type3  are typically used in high Q circuitry, such as toroidal coils and transformers,The larger Type 2 and 3 Litz designs have greater current carrying capacities necessary for highfrequency power supply, inverter and grounding applications

Type 4:

Type 4 litz cable with bundles of twisted wires and central fiber core
Type 4 litz cable with bundles of twisted wires and central fiber core

Round Type 4 Litz construction features bundles of twisted wire twisted around a central fiber core.
Optional outer insulation of textile yarn, tape or extruded compounds

Conductor: Bundles of Type 2 Litz wire and fiber core

Application: Type4,5 and 6 litz constructions all uilize at least one inert core and are used primarily in tuning circuitry for high power radio transmitters

Application: Litz Type 6 litz wire are used primarily in tuning circuitry for high power radio transmitters

Type 7

Rectangular type 7 litz cable
Rectangular type 7 litz cable

Type 7 Litz cable composes of  insulated wire braided and formed into a rectangular profile.Optional outer insulation of textile yarn, tape orextruded compounds

Conductor: Braided film-insulated wire

Application: The Type 7 braided Litz constructions  are used primarily in high frequency grounding applications, or where special inductor designs require high aspect ratio conductors ,we have listed only the most popular constructions and frequency ranges, Specific sizesutilizing almost any wire gauge are available to meetcustom er specification.

Type 8

type 8 litz cable
type 8 litz cable

Type 8 Litz composes of  single insulated strands twisted and compressed into a rectangular profile.The rectangular compacted type 8 litz constructions listed in this section are designed with copper densitiesfrom 60 to 75 percent of the cable’s cross sectional area .
Optional outer insulation of textile yarn, tape or extruded compounds

Conductor: Compacted film-insulated wires or compacted groups

Application:This type litz is particularly suited for high frequency motor,generator,transformer and inverter windings where limited space necessitates a conductor with excellent fill factor and copper density.
