Electric heating radiant tube
1. Wire-wound spiral electric heating radiant tube
This type of electric heating radiant tube consists of a heat-resistant alloy steel casing and a heater. The heater is generally made by winding electric heating wire around a heat-resistant insulating ceramic core with spiral grooves.
2. Ribbon-wound spiral electric heating radiant tube
The structure of this heater is basically the same as thefirst type, except that the heating element is wound with resistance ribbon, and the core is mostly composed of multiple grouped cores. Under the same surface load, the heat radiation area is larger, and materials can be saved. Generally, high-power point heating radiant tubes adopt this form.
3. Axial zigzag cage-type electric heating radiant tube (commonly known as squirrel-cage type)
Its structure is to bend the resistance wire (ribbon) of the heating element into a "U" shape and thread it through multiple insulating high-temperature-resistant ceramic support plates, fixed in the middle with a heat-resistant rod. This type of radiant tube has a longer service life.
