The selection of electric heating tubes should consider voltage:

The voltage specifications of the electric heating tube must be confirmed before purchase. The confirmation of this step is equal to the fixed resistance value of the equipment. The higher the voltage, the greater the power. When the selection is incorrect, it is particularly easy for the voltage to exceed the load of the electric heating tube, causing the resistance wire to melt, and even the electric heating tube to break down Conventional voltage specifications: 24V, 36V, 48V, 110V, 220V, 380V, usually rated voltage. Rated voltage of electric heating tube: The rated voltage of electric heating tube refers to the voltage specified and indicated on the outer shell of the electric heating tube during redesign, which is connected to the electric heating tube In other words, the rated voltage is the voltage that the customer requires us to process and produce. Usually 24V, 48V, 110V, 220V, 380V, etc The working voltage of electric heating tubes: (1) Multiple series power sources. For a group of electric heating tubes or electric heating tubes with multiple series power sources, the working voltage of the electric heating tubes refers to the voltage specified during the design when connected to this group of electric heating tubes (2) Single power supply. For a single electric heating tube connected to a power source, the working voltage of the electric heating tube refers to the voltage specified in the design to be connected to the component, that is, the rated voltage Note: How many electric heating tubes are connected in series or parallel here Therefore, when determining voltage, if multiple heat pipes need to be connected, it is necessary to consider whether they are in series or parallel to determine the voltage of a single heat pipe. The impact of voltage on power: When the power of the electric heating tube is determined, if the voltage is less than the designed voltage, it will lead to a decrease in power and a decrease in heating efficiency; If the voltage is greater than the design voltage, it will lead to an increase in power, a high load, and the possibility of internal wire melting or even electric heating tube breakdown
