The main factors affecting the outer diameter of the electric heating tube resistance coil are as follows:

The resistance wire is in contact with the magnesium oxide powder. After the magnesium oxide powder is filled, the compression treatment reduces the porosity of the magnesium oxide, and the resistance value of the resistance wire is reduced by 15% to 25%. At this time, attention should be paid to the influence of the coil outer diameter on the resistance drop rate. Under normal circumstances, the outer diameter of the coil is large, the resistance drop rate is also large, and unevenness occurs. In order to reduce this non-uniformity, this non-uniformity directly leads to the deviation of the rated power.

How does the heating tube suspension installation affect the outer diameter of the coil?

When heating is used, refer to the terminal grounding method. The heating pipe is grounded at one end of the output end of the heating pipe (or compensation line) through a sufficiently large capacitance (the larger the capacitance, the better). The grounding method of the measuring end is to ground the measuring end of the heated tube, that is, to ground the wire from the measuring end of the heated tube. This method has a better preventive effect on high temperature leakage interference. When choosing the power cord, you must use a heat-resistant wire that is harmless to the heating tube electrode.

Electric heating tube single-ended heater:

The electric heating tube is used for the heating medium that cannot be connected at both ends, and is suitable for the heating core box, the core transmitter and other equipment.

Electric heating tube heater:

Electric heating pipes are mainly used for air heating systems in air blowing pipes, and Shanghai heating pipes are used for blowing hot air. It can also be used as a heating element for various types of ovens and electric stoves.
