How to connect two wires of 380V electric tubular heating elements?

How to connect two wires of 380V electric tubular heating elements?

Electrical tubular heating elements wiring problems for people who don't have much contact with the electric heating tube is a very headache question.

First we need to understand the difference between the rated voltage and the supply voltage:
The rated voltage is the voltage of a single electric tubular heating elements, which will not change after the heating tube is finished. The supply voltage is the total supply voltage to which the electric heating tube is connected.

Now that we know the difference between rated voltage and supply voltage, we need to know the following questions:

1. Is the 380V heating tube a cartridge electric heating tube or a U shape heating tube or a flange electric heating tube?
2. How many 380V heating pipes are connected together with two wires?
3. Are these two wires one and zero wires in 220V power supply voltage or two wires in 380V power supply voltage?

After we understand the above problems, we can know how to connect the two wires of the 380V tubular heating elements. We hope that when you ask us about wiring, you will try to give more parameters so that we can help you solve the problem more quickly.
