Wytrzymałość prądowa przewodów elektrycznych YDYp 1,5mm2 i 2,5mm2 - TEST przeciążenia i temperatury

See a comparison of the current resistance of electrical and power cables with the most popular cross-sections of veins: 1.5 mm2 and 2.5 mm2. Connection using a kanlux connector generates increased resistance / heat release here, so you should not consider receiving heat from a 1.5mm2 to 2.5mm2 conductor, which would cool 1.5mm2. The connector is a kind of buffer that separates the wires. In addition, the veins with insulation are insulated from the shell, so they give off heat to the environment, i.e. they cool down at the connector. Therefore, in my opinion, the test can be considered very reliable as to the results. The connection of the wires is in series and exactly the same steady current flows in each vein. I am convinced that this film will allow you to draw the right conclusions that you can better assimilate and understand relative to dry theory. As you can see in the film, a larger cross-section of the vein means lower resistance, and thus, a lower temperature of the vein, insulation and coating made of polyvinite, as well as greater current resistance and long-term load. If you have a question or want to propose a scenario for another test that you would like me to do, I invite you to comment.
