Confirmation of Heating Tube Resistance - Yangzhou Darui

　Darui Electric recommends for you
The *most important core part of the heating tube is the work of the heating wire. The quality of the heating wire determines the quality of the heating tube. Studying the heating wire means studying its resistance, which determines the power of the heating tube. The resistance of the heating tube is fixed. When connected to different working voltages, different heating tube power effects appear, and the thermal effect is the same. Usually, the smaller the resistance, the larger the wire diameter of the resistance wire. Under a fixed voltage, the current passing through the resistance wire is larger. When the current exceeds the load of the resistance wire, it is prone to breakage and damage. Data shows that the resistance of the heating tube is not as small as possible; the appropriate resistance wire should be selected according to the actual situation and to ensure normal use.

　Two points for confirming heating tube resistance:

　1. Determine the resistance based on the provided rated voltage and rated power. Formula: voltage * voltage / power = resistance.

　2. The surface load of the heating wire must not exceed the standard, generally not exceeding 1.5w/cm2.

　When selecting the resistance for heating tube production, it is mainly based on the rated voltage and rated power provided by the customer. At the same time, Yancheng Jinshengda reminds us to also consider the surface load capacity of the resistance wire, thereby ensuring the service life of the heating tube.
