peamised tegurid see määravad välimine läbimõõt takistus traat mähis an elektriline küte toru on nagu järgmine:

(1) Insulation distance and insulation resistance. The insulation resistance between the resistance wire and the sleeve at high temperatures is different from that at low temperatures. However, when considering the insulation resistance itself, the larger the distance, the greater the insulation resistance between the resistance wire and the sleeve. From the perspective of heat conduction, there are certain limits. The insulation distance varies with the required insulation resistance usage temperature, but when using high-quality magnesium oxide powder as insulation, it is usually appropriate to choose 1.5-3mm. (2) The heat of the thermal conductive resistance wire is transferred to the sleeve through magnesium oxide powder, and then to the heated object. Generally, a resistance wire coil wound in a coil shape is regarded as a resistance wire with an outer diameter of d. When wrapped in insulation with thermal conductivity, the thickness of the insulation material determines the best heat dissipation. (3) The uneven resistance drop rate of the resistance wire is in contact with magnesium oxide powder around it, and the compression processing after being filled with magnesium oxide powder reduces the porosity of magnesium oxide. At this time, the resistance value of the resistance wire is reduced by about 15-25%. At this point, attention should be paid to the influence of the outer diameter of the coil in the resistance drop rate. Generally, when the outer diameter of the coil is large, the rate of resistance decrease is also large, and unevenness may also occur. To reduce this non-uniformity, as it directly leads to a deviation in the rated power.
