Definition of power cord

- Apr 23, 2019-

The power cord is a wire that carries current. Usually the way of current transmission is point-to-point transmission. The power cable can be divided into an AC AC power cable and a DC DC power cable according to the application. Generally, the AC power cable is a wire that passes a relatively high voltage AC. Such a wire material can be formally produced due to a high voltage and a unified standard to obtain a safety certification. The DC line basically passes the DC power with lower voltage. Therefore, there is no strict AC line requirement in terms of safety. However, for safety reasons, countries still require unified safety certification.
