RUPALIT® 05 Litzwires provide a low cost alternative compared with solid wire.


Technical and Economical Benefits

  • Primary and secondary windings are wound in one cost saving   operation
  • Short circuits and incorrect connections are avoided
  • Quicker and easier to wind than solid wire
  • Primary and secondary are distinguished by colour coded enamels
  • Skin effect reduced

Application examples
