What kind of electric heating tube can be called a high-density single head electric heating tube

High density single head electric heating tubes are a type of electric heating tubes, and ordinary single head electric heating tubes are often used in the market to impersonate high-density single head electric heating tubes. Hongchuang Electric Heating will briefly introduce what kind of electric heating tube can be called a high-density single head electric heating tube.

1. According to the heating time, under the test voltage, the time for the electric heating tube to rise from the ambient temperature to the test temperature should not exceed 15 minutes.

2. Based on the rated power deviation, under sufficient heating conditions, the deviation of the rated power of the electric heating tube should not exceed the specified range.

3. Check the insulation resistance. During the factory inspection of the electric heating tube, the cold insulation resistance should not be less than 50M Ω.

4. Based on the insulation withstand voltage strength, the electric heating tube should be maintained for 1 minute under the specified test conditions and voltage, without flashover or breakdown.

When purchasing high-density single head electric heating tubes, it is advisable to test the above four aspects more. If the test results differ from the above, it is necessary to consider whether the electric heating tube is a qualified high-density single head electric heating tube.

What environments will affect the use of electric heating tubes

In daily work, the working environment has a significant impact on the power of electric heating equipment. Although there is no clear definition of the impact between electric heating pipes and the working environment, from specific examples, the impact of environmental factors in the use of electric heating pipes cannot be ignored. What environmental factors will affect the use of electric heating tubes? Hongchuang Electric Heating will briefly introduce to you:

1. Air factor: Electric heating tubes still have requirements for air humidity in the environment, which cannot exceed 95%. And there must be no flammable, explosive or corrosive gases present. The working voltage of the external connection of the electric heating tube cannot exceed 1.1 times the rated voltage. Before operating the electric heating tube, it is necessary to ensure that the shell is effectively grounded to avoid accidents.

Cop2, geographical temperature factor: altitude does not exceed 1000m; The ambient temperature is -20~50 ℃.

3. Shock and vibration: The fluctuation of the three power supplies of the equipment shall not exceed ± 5%. The electric heating tube should be placed smoothly and should not exhibit significant fluctuations.

Pay attention to the above environmental factors, which can ensure the risk-free and efficient operation of the electric heating tube equipment, and also have a positive impact on extending the service life of the electric heating tube. If you encounter any problems while using the electric heating tube, please feel free to contact Hongchuang in a timely manner, and our technical personnel will help you solve your problems as soon as possible.
