In the Chinese electric heating industry, there is a model that has been known for a long time: M3. In the late 1990s, due to the widespread use of electric heating tubes in China, there are now many styles of electric heating tubes. In the southern region of the Yangtze River in China, the electric heating tubes used for this one end production model are called single head electric heating tubes or single end electric heating tubes, which are very similar. Overseas, it is called a cartridge heater, which is also a similar term. Due to the cylindrical shell of the cartridge, one end is also blocked, which is a clever comparison with the Chinese term for a single head electric heating tube.
Single headed tube, also known as single ended electric heating tube or cartridge electric heating tube, is a type of electric heating tube (tubular electric heating element).
Currently, the performance requirements for single headed pipes comply with relevant national standards. Single headed pipes have the following requirements:
1. Under the condition of sufficient heating, the deviation of the rated power of the component should not exceed the range specified below; For components with a rated power of less than or equal to 100W, it is ± 10%.
2. The leakage current of a single head electric heating tube, cold state leakage current, and leakage current after water pressure and tight sealing attempts should not exceed 0.5mA; The thermal leakage current at office temperature should not exceed the calculated value in the formula, but the maximum should not exceed 5mA.
3. The heating time should be more than 15 minutes for the component to rise from the background temperature to the test temperature under the test voltage. A bit of the company's power is done very accurately, for example: Taizhou Jiayi Single End Electric Heating Tube Factory; In the Yancheng area, some companies can achieve a resistance deviation of only 1 Ω from+5% to -5%, such as Annai Electric Heating. For components with a rated power greater than 100W, it is+5% to -10% or 10W, whichever is higher.
