From a main power source, an appliance can work if a power cord can conduct electricity to it. Power supply cords are flexible cords that consist of two plugs on both ends. The ends consist of a male plug and a female plug. What connects both ends is the cable assembly which is made up of copper stands covered with insulating material such as a rubber jacket or a polymer. These copper strands conduct electricity from the main power source to the appliance. You can read more info here.
Power cord sets are used anywhere the appliance of electrical equipment is used but the power supply cord is fixed on the electrical equipment itself. There are also extension power cords which are used when the equipment is far from the power source. Applications for extension cords can be used in sound equipment, lighting, shop equipment, and other domestic equipment. The standard for North America electrical plugs, electrical receptacles configuration, and cord voltage capacities is the NEMA power cords. These American standards are very different from those set for the international market which is called international power cords. A plug adapter has to be used in order for a NEMA plug to fit in an international socket. Learn more info, go here.
One end of the power supply cord is the male plug which is connected to the power source. And, the female is the plug that goes to the appliance or electrical equipment. Many places have different voltage standards and electrical receptacle configurations, and this is the reason why power cord manufacturers make power cords depending on the region and country they are making it for. It is not possible to interchange power cords since voltage and receptacles are not the same. There are differences with American and international standards.
There are many factors to consider when you are selecting the type of power cord that you need for specific applications. You need to check the specifications that are followed by the manufacturer of power cords including current rating, voltage rating, safety, jacket materials, wire shape and size, length and maximum cable temperature. The jacket materials that suits the cords best is determined by the application. The available jackets have the following materials: rubber, polychloroprene, thermoformed from PVC, and textile construction. The amount of voltage that will pass through the cord determines the size of the power supply cord or the electrical wire needed.

Power supply cords you find in the market are of different types. These different types of power cords have different gauge sizes, awg size, heavy, mild, or low application, various jackets and insulations. The different power cords include international power cods AC power cords, extension cords, electrical plugs, power supply cords, international cord sets, etc.
