What is a single-head electric heating tube? A single-head electric heating tube is a kind of tubular heating element. In the electric heating industry, there is a model called M3 for a long time.
The structure of the single-head electric heating tube is the same as that of the electric heating tube. It is generally composed of the following parts: insulator, sealing material, lead rod, filler, heating wire, metal sheath, and terminal.
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, pollution-free, and low price. At the same time, it saves electricity and is safe to use. It can be bent into various shapes, light, and disassembled. Easy to install.

Electric heating tube performance requirements:
1. The heating time is under the test voltage, and the time for the component to rise from the ambient temperature to the test temperature should not be more than 15min;
2. The deviation of rated power should not exceed the range specified below under the condition of sufficient heating; for components with rated power less than or equal to 100W: ±10%. For components with a rated power greater than 100W, it is +5% to -10% or 10W, whichever is greater. The power of some companies is very accurate.
3, leakage current cold leakage current and leakage current after water pressure and sealing test should not exceed 0.5mA; hot leakage current at working temperature should not exceed the calculated value in the formula, but the maximum should not exceed 5mA.
