–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.
