1、DC Power cords are used in a large amount in the wire and cable industry. For example, power cords for mechanical equipment, power cords for home improvement, electrical appliances, charging devices, lighting, instrumentation, etc. are all inseparable from the use of power cords. Power cords are wires used to transmit current. There are two types of power cords according to their uses, AC power cords and DC AC power cords. The AC power cord is an AC wire with high transmission voltage. Because of the relatively high voltage, this kind of wire needs to obtain safety certification according to a unified standard before it can be formally produced. The DC power cord is a wire that passes direct current with a lower voltage, so the safety requirements are not as strict as the AC power cord.
2 、There are many types of power cords, what are the common types? 1. Universal rubber-plastic power cord: suitable for connection and internal installation of power, lighting, electrical installations, instruments and telecommunication equipment with AC rated voltage of 450/750V and below; 2. Rubber-plastic flexible power cord: mainly suitable for medium and Connection of light mobile appliances (household appliances, power tools, etc.), instrumentation, and power lighting; the working voltage is AC 750V and below, and most of them are AC 300C.
