What is the difference between the rated voltage and the working voltage?

1. Rated voltage

The rated voltage refers to the voltage connected to the electric heating tube specified in the design and marked on the shell of the tube. Or in other words, the rated voltage is the voltage given by the customer when we are required to process and produce. Generally there are 24V, 48V, 110V, 220V, 380V and so on.

2. Working voltage

For a single electric heating tube connected to the power supply, the working voltage refers to the voltage connected to the element specified in the design, that is, the rated voltage.

For a group of electric heating tubes connected in series to the power supply, the working voltage refers to the voltage connected to this group of heating tubes specified in the design.

If you don’t distinguish between the rated voltage and the working voltage, there will be two situations when you use it improperly:

1. The electric heating tube does not generate heat.

2. The heating tube temperature is very high.

So we should understand the difference between these two voltages before applying the electric heating tube.
