The difference between heating tube 220V and using 380V:

The difference between heating tube 220V and using 380V:

1. Suitable for different electrical appliances:

The voltage of 380V is the voltage between two phase lines and is generally used in high-capacity electrical appliances such as power demand; A voltage of 220V is the voltage difference between a phase line and a neutral line, generally used in lighting and small appliances.

2. Different applicable electrical phases:

380V is generally suitable for controlling electrical equipment such as three-phase motors that do not allow phase loss, usually taking A and C phases. There is a possibility of 2/3 of the magnet being released due to a phase loss fault. It is easy to check faults with an electric pen; 220V control is generally suitable for individual power supply. Multiple shared. There is no connection between load and control. Using an electric pen to check for faults is average.

3. The optional wires are different:

A 380V heating tube requires a three-phase power supply, so when selecting wires, a thinner one is sufficient; When selecting wires for 220V heating tubes, thicker ones are necessary, but the number of wires needed is less than that of 380, which can be said to be different.

2, There is no specific distinction between safety and it is not closely related to voltage. The heating efficiency and safety of 380V and 220V heating tubes are the same at the same power.

What is the difference between heating tubes 220V and 380V?, As a heating element, the electric heating tube also serves as the heating element in the equipment we apply. However, we need to pay attention to and understand the difference between the 220V and 380V of the heating tube and their wiring methods.

What is the difference between heating tubes 220v and 380v

There are 380V and 220V heating tubes, and the usage depends on the specific situation of the equipment. The current of a 380V heating tube is smaller than that of a 220V heating tube under the same power, which means that the current of a 1WK 380 heating tube is 2A, while the current of a 1WK 220V heating tube is about 4.5. The 380 heating tube requires a three-phase power supply. So when choosing wires. A finer one is sufficient. When selecting wires for 220V heating tubes. It needs to be thicker, but it requires fewer wires than 380, which can be said that each has its own strengths.

The heating efficiency of 380V and 220V heating tubes is the same at the same power. The security is the same. 380V coils were commonly used in previous electronic control systems, and directly using a two-phase power supply could provide phase failure protection. Nowadays, safe electricity use is advocated, and isolation transformers are used to provide control power. In ordinary equipment, 220V control power is generally used, while 110V is generally used as the control power voltage level for machine tool electrical control.
