The spiral heating tube
Key words:
The spiral heating tube is a tubular electric heating element with a structure in which an electric heating wire is placed inside a metal tube and the gaps are tightly filled with crystalline magnesium oxide with good thermal conductivity and insulation. The two ends of the electric heating wire are connected to the power supply through two lead out rods. It has the advantages of simple structure, long service life, high thermal efficiency, good mechanical strength, and can be bent into various shapes for safe use. Using high-quality materials and strict process technology, we produce electric heating tubes with excellent electrical insulation performance and extremely high electrical strength.
