isovac high-perm 235-35 A HC
Manufactured in the most modern production lines, this fully processed isovac® grade exhibits highly homogeneous properties across the width and length of the entire strip. The result is excellent and consistent processability in the manufacture of highly efficient electrical components. Its high thermal conductivity and optimized texture make isovac HP 235-35 A HC (high-perm/high-conduc-tivity) ensure rapid heat dissipation in combination with increased magnetizability and low specific total loss. This makes innovative design strategies possible for electrical machinery.Upon request, isovac HP 235-35 A HC can be supplied with an electrical steel insulation system and can be used directly in as-delivered condition.
Convincing advantages: » Lower cooling power necessary through higher thermal conductivity than that of standard isovac® grades (conductivity increased by up to 20%)
» Increased performance achieved by increasing torque based on higher magnetizability (im-provement by up to 0.05 T at J25, J50, J100)
» Best processability through consistent mechan-ical properties and homogeneous, clean sur-faces
» Excellent stackability resulting from high dimen-sional accuracy in rolling direction and perpen-dicular to rolling direction (thickness tolerance)
» Innovative electrical steel insulation systems upon request
The specialist for high permeability with high thermal conductivity
