For terminal wire processing, the conductor wire must have enough strength. If the strength is not enough, it is easy to break due to some external forces, such as strong wind, icing or improper handling during repairs; if you choose a wire with a thin section , It is easy to cause overheating when using overload current, which will damage the protective insulating layer, which will seriously cause the circuit to catch fire; and the selected wire must not have excessive voltage loss.
Therefore, when processing the terminal wire, we are selecting the conductor wire, which needs to be selected according to your circuit situation. If you choose a low voltage, you need to choose the thickness of the conductor wire according to its heat generation, and then test its voltage loss and strength. If it is high voltage, you need to select the conductor wire according to its current situation, and then measure its heating and voltage loss.
