The electric heating tube is a heating element that converts electrical energy into heat after being energized, and is suitable for a variety of heating media, such as oil, water, and chemical media. Tubular heating elements can be processed into U-shaped, wave-shaped, spiral-shaped, straight-rod-shaped and other shapes as required.

Tubular heating elements can be processed into U-shaped, wave-shaped, spiral-shaped, straight-rod-shaped and other shapes as required. The cross-section of the component can be divided into circular, elliptical, rectangular, triangular and other categories. Components are divided into single-ended or double-ended wiring, each end has 1 to 3 wiring rods. It has the characteristics of high thermal efficiency, long service life, convenient installation and stable work.
How to Confirm the Specification?
1. Voltage: 220V or 380V, power: what is the wattage KW
2. Thread specification: M18 (corresponding to the installation hole diameter 18mm)
3. Center distance of terminal (mounting hole): about 55mm, adjustable by 1 cm difference
4. The length of the tube: according to the actual equipment requirements
Three-phase connection of electric heating tube
In a 380 volt three-phase four-wire circuit, the voltage between any two live wires is 380 volts, and any live wire and neutral wire can form 220 volts. This system can form three power sources: single-phase 220 volt power supply, single-phase 380 volt power supply, and three-phase 380 volt power supply. The first type is used more for household, the third type is more used in factories, and the second type is used less, only AC welding machine often uses single-phase 380V power supply.
