Fields of application
  • Electromagnet construction
  • Generator construction
  • Transformer construction
Product advantages
  • Very resistant to high temperatures
  • Insulation class C
  • Weight reduction of around 50% compared to a copper coil with comparable electrical properties
  • No “hot spots” within the coil due to high heat dissipation; therefore, no additional insulation is necessary
  • anoxal®E coils don’t require more installation space than copper coils with comparable electrical properties (fill factor > 90%)
