1. What is a single-head electric heating tube
Single-head electric heating tube is also called single-ended electric heating tube and cartridge electric heating tube (r). It is a kind of electric heating tube (tubular electric heating element). It has a certain name in China's electric heating industry. Long term model number:. In the late 1990s, due to the widespread use of electric heating pipes in China, many electric heating pipes for molds with one end out of the wire were called single-head electric heating pipes or single-ended electric heating pipes in southern China.
In foreign countries, it is called a cartridge heater, which is also a figurative name because the cartridge shell is cylindrical and one end is blocked. In China, it is called a single-head electric heating tube, which is a coincidence.
2. Structural composition of a single-head electric heating tube
The typical structure of a single-head electric heating tube is the same as that of an electric heating tube and generally consists of the following parts: insulator, sealing material, lead rod, filler, heating wire, metal guard Bushings, 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 is easy to disassemble and assemble. So what is a single-head electric heating pipe? What are the performance requirements for electric heating tubes? Let’s take a look below. &

3. Application scope of single-head electric heating tube:
Mold heating has been accepted by a wide range of customers in modern industrial applications.
, in plastic machinery heating system.
, pharmaceutical production line.
, Laboratory heat treatment test.
, chemical industry, etc.
4. Performance requirements for single-head electric heating tubes:
. Heating time: The time for the component to rise from the ambient temperature to the test temperature under the test voltage should not be greater than minutes
. Rated power deviation: when fully heated Under the conditions, the deviation of the rated power of the component should not exceed the following specified range; for components with a rated power less than or equal to: &;%, for components with a rated power greater than +%-% or the greater of the two.
.Leakage current: Cold leakage current and leakage current after water pressure and sealing tests should not exceed. Hot leakage current at operating temperature should not exceed the calculated value in the formula but the maximum exceeds
.Insulation Resistance: The cold insulation resistance during factory inspection should not be less than &; The insulation resistance after long-term storage or use after sealing test should not be less than &;
. Heat resistance: The component should be under the specified test conditions and test voltage. Withstand multiple cycle heat resistance tests without damage.
