Transposed Conductors

 

Transposed conductors are composite conductors formed by paralleling multiple insulated single-strand wires and then regularly transposing them. They are primarily used in the windings of high-power transformers, motors, and reactors.

Name:Transposed conductors

Each individual wire typically consists of:

Enamelled copper wire / Enamelled aluminum wire, Paper-insulated copper wire

The entire bundle of wires can be covered with:

Insulating paper

Insulating film

Composite insulation

 

Applications:
Oxygen-free copper flat wire Widely used in: transformer windings (oil-immersed/dry-type), motor stator windings,

generators, new energy vehicle motors, high-frequency transformers, inductor coils, high-power power supplies,

and power electronic equipment.
