Litz Wire

Litz Wire Image

Since 1977, Rubadue Wire Company has been supplying custom engineered solutions to the electronics and magnetic winding industries.

Rubadue invented triple insulated wire and since that time has been the leader in high temp and high performance winding wire. We continue to offer innovative solutions to help designers of magnetic components meet the ever-increasing demands for smaller and more efficient products. Following the acquisition and integration of Kerrigan-Lewis, Rubadue is able to offer a wider range of Litz Wire products in both extruded and non-extruded options to better meet customer requirements.

Litz wire is made of several strands of enamelled magnet wire that are bunched or stranded together.  It is used where losses caused by the skin-and proximity effect on a single wire are too high due to the operating frequency.  At the same time the operating temperature is reduced by its use.  Litz wire has much greater mechanical flexibility than a single wire with the same cross-section.​
