Is 220V or 380V connected to both ends of the U type heating tube?

As a qualified electric heating tube sales, you not only need to know how to design electric heating tubes but also very familiar with the heating tube wiring, because you will often encounter customers asking you like " U type heating tube wiring at both ends Is it 220V or 380V?” This question cannot be explained clearly in one sentence or two sentences, so here I will sort out its answers for your common reference.

  The voltage at both ends of the  U type heating tube may be 220V or 380V, depending on the rated voltage determined by the customer when ordering it? How to determine the rated voltage of the  U type heating tube?

We must be clear about the following points:

(1) How many  U type heating tubes are connected together?

(2) What is the power supply voltage?

(3) What kind of wiring method is used?

Knowing the above three questions, we can answer the question of whether the two ends of the U-shaped heating tube are connected to 220V or 380V.

Practical example:

       If three  U type heating tube are connected together, and the power supply voltage of 220V is connected by the delta connection, then the rated voltage of the  U type heating tube is 220V. Similarly, three  U type of heating tube is connected together. If you use a star connection to connect to a power supply voltage of 380V, the rated voltage of the  U type heating tube is also 220V.

       Through practical examples, I think everyone should know that the customer’s question "Is the  U type heating tube connected to both ends of 220V or 380V?" There are two possibilities. It may be 380V or 220V or other voltages. The wiring method, the total number of wiring, and the total power of the wiring are judged. If there are friends who don’t know about problems like this, you can consult our company's salesperson, and we will answer you carefully.
