How to choose the resistance wire diameter of the electric heating tube during production?

A.0.4mm Maximum operating temperature: 950—1000℃
B.0.3mm Maximum operating temperature: 900—950℃
C.0.2mm Maximum operating temperature: 850—900℃
D.0.15mm Maximum operating temperature: 820—850℃
The above is to select different wire diameters of the resistance wire according to the temperature. First of all, according to the temperature requirements, the wire diameter should be determined according to the thick wire of the heating tube diameter. If the diameter of the electric heating tube is too small, choose too thick resistance wire. The insulation layer will inevitably be insufficient, which will affect the withstand voltage and service life of the heating tube. Depending on the diameter of the tube, the minimum insulation thickness of the insulation layer must be greater than or equal to 1.5mm, so that the withstand voltage of the heating tube will be guaranteed!
