High-density cartridge electric heating tube is a type of electric heating tube. Some unscrupulous merchants in the market often use general cartridge electric heating tubes to impersonate high-density cartridge electric heating tubes. In order to help customers distinguish , today LAIYUAN tells you what kind of electric heating tube can be called a high-density cartridge electric heating tube.      1. Look at 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. Look at the deviation of the rated power. Under the condition of full heating, the deviation of the rated power of the electric heating tube should not exceed the specified range.      3. Look at the insulation resistance. The cold insulation resistance of the electric heating tube should not be less than 50MΩ during the factory inspection.      4. Looking at the dielectric strength, the electric heating tube should be kept for 1 min under the specified test conditions and test voltage without flashover and breakdown.      When you buy a high-density cartridge electric heating tube, you may wish to test the above four aspects more. If the test results are different from the above, you should consider whether the electric heating tube is a qualified high-density cartridge electric heating tube.
