1. The partial break of the copper wire inside the plug power cable is called a half-break. When the current flows through the half-break, the circuit suddenly becomes narrow, causing overload and high heat. 2. When using v, it should be noted that it cannot be bundled; because the plug power cord i...

The complete naming of wires and cables is often complicated, so people sometimes use a simple name (usually the name of a category) in combination with the model specification instead of the full name, such as "low voltage cable" for all plastic insulated power of 0.6/1kV class. cable. The wire and...

Our common power sources, including power adapters and chargers, are all switching power supplies. The switching power supply is a power supply that maintains a stable output DC voltage by controlling the ratio of the time period in which the switching transistor is turned on and off. The switching ...
