Six Factors affect the quality of electric tubular heating element

- Mar 27, 2020-

  1. Electric strength: the factors affecting the electric strength of electric tubular heating element mainly include the thickness of insulating layer, the quality of insulating layer material, the length of electric tubular heating element, the radius of twists and turns and the number of twists and turns. Jaye industry is usually able to achieve 2000V, 1s and 0.5mA breakdown current on the cold state withstand voltage of electric heating tube.       

  2. Insulation: the sealing technology of the electric heating pipe is the most important factor affecting the insulation of the electric heating pipe. Jaye industry's heating elements can usually achieve more than 1000 megaohms.        

  3.  Leakage current: mainly related to the temperature when the electric tubular heating element is used, the application voltage of the electric tubular heating element, the heating length of the electrictubular heating element, etc. An important audit target of high temperature electric tubular heating element.       

  4.  Power accuracy: mainly related to the quality of resistance wire and the technical level of the manufacturer. Jaye industry needs to do temperature coefficient experiment before mass production to determine qualified cold resistance of power scale.      

  5. Life: the life of electric heating tube is not only related to the quality of resistance wire, but also related to the quality of magnesia powder and the selection of resistance wire diameter. Jaye industry is able to make high temperature electric tubular heating element with external load below 8W / cm2. When selecting the diameter of the resistance wire, it is necessary to check the external load of the resistance wire to meet the life demand.      

  6. Corrosion resistance is a common problem in water heating tubular heating element and barbecue electric pipe. In addition to the reasonable selection of information, it is also related to the heat treatment of the electric heating pipe and the appearance of the electric tubular heating element.
