　　Decide what is the probe carrying current?

　　In addition to some external factors that will reduce the current carrying capacity of the probe in a specific environment, the internal factors of the probe that determine the meteors of the probe are more critical, which are mainly determined by the following three points:

　　1. Thermal conductivity of insulating layer

　　In addition to preventing electric shock, the insulating layer also serves as a flame retardant. If the thermal conductivity of the insulating layer material is better, the flame retardant performance will be better. So the insulation material is good or bad

　　In another aspect

　　The current carrying capacity of the probe is heard.

　　2. Material conductivity

　　The key is to look at the conductor material, such as common copper wire and aluminum wire. The conductivity of copper is at least 30% higher than that of aluminum. When necessary, there may be silver lines. In addition to looking at the substance of the material, we also need to look at the purity of the material. For example, the copper material, the highest purity red copper, has a much higher conductivity than the second-class brass.

　　3. Probe core area

　　It is also commonly referred to as "wire diameter", such as 2.5 square millimeters, 4 square millimeters, etc. commonly used in decoration, which refers to the wire diameter. It should be noted that the current carrying capacity is not the cross-sectional area of the entire wire. It is the cross-sectional area of the conductor in the line. The thicker the line, the greater the current-carrying capacity.
