Electric heating element is more and more widely used in life, electric heating element market is also more and more large, people's demand for it is also more and more high, so we should strictly control the quality of the electric heating element, In the performance requirements of the electric heating pipe we are to do the position.
During the test, the temperature change of the electric heating element must be controlled within the standard range. In general, when the test voltage is used, the temperature of the element must be raised to the test temperature within a quarter of an hour. Resistance is the key component of electric heat element, so the resistance quality directly affect the advantages and disadvantages of the electric heating tube, cold insulation resistance of qualified products shall be greater than 50 m Ω.
When the electric heating tube is tested for compressive strength, there is no breakdown and flashover within one minute under the test conditions.Customers in the choice of electric heating pipe must be based on their own use, choose their own appropriate electric heating element.
