What is the difference between resistance wire and heating wire, and what are the main requirements for use 2

When using resistance wires and heating wires, the following points should be noted:

1. Material selection: Choose the appropriate material according to the application requirements. Resistance wires may be made of various materials, while electric heating wires need to be made of materials that are resistant to high temperatures and have high electrical resistivity.diode

2. Rated power: Ensure that the rated power of the resistance wire or heating wire used matches the power supply and intended use, avoiding the risk of thermal damage or fire caused by overload.

3. Temperature resistance: For electric heating wires, it is necessary to consider their stability and durability after long-term heating, and choose materials that can withstand continuous high temperature operation.diode

4. Thermal expansion: Metal will expand when heated, so the impact of thermal expansion on the entire structure should be considered in the design.diode

5. Insulation and safety: When electric heating wires work at high temperatures, good insulation must be ensured to prevent electrical short circuits or electric shock accidents, and corresponding safety standards must be followed.diode
