Specialities , Corner insulation and fastenings
Micafil : Laminates made by Micafil are temperature class F with high tracking resistance - for more information please email us on enquiries@calidus.co.za
Corner insulation : Micafil offers a complete set of generator rotor insulations including corner and interturn insulation
Specialities :Micafil also supplies specialities such as insulations designed for specific applications with
customised compositions of layers.Special finishes such as a rough surface as well as cutouts
for ventilation are possible .
Fastenings :Fastenings made of Micafil or Vetresit are available (which has comparable in some cases superior
mechanical properties as those made of metal).
