Definition of power cord:
A power cord is a wire that transmits current. The way current is normally transmitted is point-to-point. Power cables can be divided into AC power cables and DC power cables according to their uses. Generally, AC power cables pass through AC cables with high voltage. Such cables can be formally produced by the safety certification party with unified standards due to high voltage. And DC line is basically through low voltage DC, so the safety requirements are not strict AC line, but for the sake of safety, countries still require unified safety certification.
Technical standards: (1) In accordance with sdJ161-85 power System Design Technical Regulations issued by the Ministry of Electricity •Previous:
