Introduction to 380V Single-Head Electric Heating Tube
A 380V single-head electric heating tube is a tubular heating element that converts electrical energy into thermal energy. It typically consists of a metal tube, an internal resistance wire, and filling material, providing stable heat output suitable for various heating applications.
Basic Principle
The working principle of a 380V single-head electric heating tube is to generate heat through the Joule heating effect when current flows through the resistance wire. The resistance wire is placed inside the metal tube, surrounded by good insulating materials such as magnesium oxide powder, to ensure good insulation between the resistance wire and the metal tube and to facilitate uniform heat distribution.
