1. Structural composition of export-quality single-head electric heating tube heating rod:
The typical structure of a single-head electric heating tube is the same as that of an electric heating tube. It generally consists of the following parts: insulator, sealing material, lead rod, and filler , heating wire, metal sheath tube, terminals. The single-head electric heating tube has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life, no pollution, low price, etc. At the same time, it saves electric energy, is safe to use, can be bent into various shapes, is lightweight and can be disassembled. Easy to install.
2. Performance requirements for export-quality single-head electric heating tube heating rods:
According to relevant national standards, electric heating tubes have the following requirements:
, Heating time
Under the test voltage, the element The time from ambient temperature to test temperature should not exceed;
, rated power deviation
Under sufficient heating conditions, the deviation of the component's rated power should not exceed the following specified range;
For Components with rated power less than or equal to: &;%.
For components with a rated power greater than +%~-% or, whichever is greater.
Some companies can achieve very accurate power, for example: Taizhou Jiayi Single-ended Electric Heating Pipe Factory
Here in Yancheng area, some companies can achieve +%~-%, and the resistance value deviation is only& ;, such as An Nai electric heating.
, leakage current&;/&;
The cold leakage current and the leakage current after the water pressure and sealing test should not exceed.;
The hot leakage current at the operating temperature should not exceed the formula The calculated value in , but the maximum does not exceed;
/(&;.)
&;Thermal leakage current
&;Heating length
-Operating temperature ℃
When multiple components are connected in series to the power supply, the leakage current test should be conducted on this group of components as a whole.
, Insulation resistance
During factory inspection, the cold insulation resistance should not be less than &;;
After the sealing test, the insulation resistance after long-term storage or use should not be less than &;;
The thermal insulation resistance at operating temperature should not be lower than the calculated value in the formula, but the minimum should not be less than &;;

, Insulation withstand voltage strength
The components should be maintained under the specified test conditions and test voltage, There is no flashover or breakdown phenomenon.
, Ability to withstand power on and off
The component should be able to undergo multiple power on and off tests under the specified test conditions without damage.
, overload capacity
The component should withstand multiple cycle overload tests under the specified test conditions and input power without damage.
, Heat resistance
The component should withstand multiple cycle heat resistance tests under the specified test conditions and test voltage without damage.
