Conductor material
VEOX – produced from anodised aluminum strip
VEOX
The Conductor Material produced from Anodised
Aluminium strip
Why VEOX ?
High temperature resistance
Insulation class C
Low weight electrical coils
50% weight advantage compared to similar copper coil
Extremely compact coils (Filling factor > 90%)
Due to this fact VEOX coils do not require any more space than comparable copper coils
Excellent heat dissipation; therefore no undesirable hot spots occur in coils
No additional insulation of any type is necessary
