Electrical Power Supply Cords

Power Supply Cords is a physical medium of Supplying electricity which can be detached from the main power source to any electrical appliances. Power Supply Cords are flexible cords with electrical plugs at both the ends, one male and one female. The wire cable connecting both ends are termed as cable assembly which consists of a conducting medium, basically copper strands that covers the cords fully and acts as an insulating material and cover the outer area with either polymer or rubber jacket which protects the wire.

Power Supply Cords is the one end that is permanently fixed to that electrical equipment or appliance, and the power cord sets is that cord set that can be utilized anywhere that electrical appliance or equipment is used. It can be used in office, industries, commercial and domestic area. Extension Power Cords are the long wire cable or the cord set that helps the equipment to be connected to any electrical supplies or the source which is far away from the place of that equipment where it is being used. These extension power cords are used in various applications like lighting, sound equipment, shop equipment and in many other domestic settings. NEMA power cords are the standard for North America Electrical plugs, cord Voltage capacities and electrical receptacles configuration. These are according to the North America Standards rest is different standards that are set for International market also termed as ‘International Power cords’. There are also plug adapters to reconcile NEMA Plugs with International Sockets.

Male plug is One End of the power supply cord that connects the electrical receptacle, electrical outlet or power supply and the female plug that connects to the electrical equipment or the appliance. Power Supply cord manufacturers manufacture power cords according to different regions and countries as they have some different voltage standards and electrical receptable configurations which may or May not interchangeable with cords from other locations. The North American standards are termed as National Electrical Manufacturer’s Association (NEMA) standards for power supply cords and they are different from the International Standards. NEMA standards have come out with 15 different types of power supply cords which cannot be used or interchanged outside North America.

Consider many factors While Selecting the power cord type for different applications. Power cord manufacturers follow various specifications that include voltage rating, current rating, jacket material, safety, length, wire shape and size and maximum cable temperature. The application determines the type of jacket material is best suited for that cord. Jackets also range from thermoformed from PVC, rubber, polychloroprene and textile construction. The size of power supply cord or the electrical wire is determined by the amount of voltage that will be passed through the cord. The NEMA sets company standards for both male electric plugs and female electric plugs. An Electric plug is polarized when the physical characteristics of the blades allow the plug to be connected to the electrical outlet in only one way. Polarization and grounding is necessary for increasing higher voltage appliances and electrical equipment that could be higher risk of electric shock when they become live.

There are a variety of power supply cords in the market depending upon its gauge sizes, application for which it will be used (heavy, mid, low), awg sizes, insulation’s and various jackets. It includes International Power Cords, Cord Sets, AC Power Cords, Electric Cords, Electrical Receptacles, Electrical Plugs, NEMA Power Cords, Cord covers, Power Supply Cords, Extension Cords, Cable Assembly and Plug Adapters & Plug Covers. All the above Electrical plugs and wire cables are used in different applications with high, mid and low density.
