Single ended tubes are widely used in the process of mold electric heating tubes and other industrial electric heating equipment. Due to their frequent use, it is common to find short circuits between two lead wires. Therefore, many customers change clothes due to issues with the magnesium oxide rod and magnesium oxide powder in the winding process. Therefore, single ended tube manufacturers are required to change the original 95% magnesium oxide to 98% or even 99% pure magnesium oxide, So as to increase the probability of two outgoing lines not having a short circuit. Of course, we cannot deny that magnesium oxide powder is the most commonly used. Poor quality unmodified magnesium oxide powder can absorb moisture from the air, causing a short circuit in the single ended tube. The phenomenon of short circuits in the two leads of the single ended tube is not always due to this reason.
The above are all phenomena of short circuits between single ended tube leads.
