Litz Wires

Rubadue Wire insulates a wide range of litz wires. If you’ve never heard of litz wire, don’t worry; our team is here to go over how litz wire can transform your electrical wiring solutions!

What is Litz Wire?

Litz wire is made of several strands of enamelled magnet wires 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. Litz wire reduces operating temperature, skin effect losses, and proximity effect losses by distributing the electrical current among multiple independently insulated wire strands at the same time. It has much greater mechanical flexibility than a single wire with the same cross-section.

Litz Wire Specs:

  • Individual Wire Size Range: 50 AWG (0,02mm) to 12 AWG (2,05mm)
  • Total Number of Wires: From 2 wires to over 5,000 wires
  • Total Conductor Diameter: Overall twisted diameter up to .325” (8,3mm)
  • Temperature Class: From 155°C up to 220°C
  • Optional Coatings: Nylon serve in single- or double-layer extruded insulations such as ETFE, FEP, or PFA. Other options are also available. Contact us for more details.
