Product Description

Product Description

Product Description:
    Enameled Copper Wire is one kind of magnet wire which is consisted of bare round copper as the conductor and multi-layer insulation layers. The multi-layer insulation layers can be polyester, modified polyester or polyester-imide and so on.
Our Enameled Round Copper Wire is one kind of enameled wire which has high heat resistance. Its temperature class can be from 130ºC to 220ºC.

    Copper is the standard used conductor material with excellent conductivity and very good windability. For special applications a wide variety of conductor materials is offered,  alloys of copper for special characteristics like higher mechanical strength or bending performance.
