High
degree of insulation, guaranteed by the use of
the best available materials, such as mica and steatite ceramics;
High power dissipation
because of the wide cooling surface of the cut resistor bands;
Capacity to withstand permanent
overloads without demage or alteration, even if
temperatures reach 800°C;
High heat capacity available
from the use of thicker sheets;
Low resistance variation
with temperature as a result of employing high quality alloys.
