The Alpha resistor components consist of fully welded wirewound resistors, mounted in silica sand, insulated with MICANITE and mounted in an anodised aluminium house. The base material is high temperature MICANITE which is long time stable at 700°C and short time resistant up to 1000°C. These resitors have high resistance to temperature changes.
The resistors comply with IP50 giving electrical and thermal protection.
We can provide you with THERMAL SIMULATION corresponding to all resistor types and resistor values. By using these models we are able to calculate the temperature rises in the resistor wire and on the surface for all possible load applications. We offer our assistance to our customers to find the optimum solution for any situation.
