A Closer Look at AC Power Cords

Electric currents whose main characteristic is the periodically alternating directions are called AC or alternating currents. AC is the opposite of DC, whose current is flowing only in one direction.You can find AC as the electrical supply that is used in residences and in building establishments. The sine waveform is waveform usually assumed by an AC current.To connect an appliance to the AC power supply, consumers make use of a power cable or a line cord to connect to the wall socket that directly connects to the mains electricity supply. A general purpose AC circuit’s electrical supply can also be called as “mains electricity.”

AC current was first applied to practical circumstances in 1855 by the inventor, Guillaume Duchenne. While developing electrotherapy, Guillaume Duchenne had noticed AC’s superiority over DC is inducing muscle contractions.Electrotherapy is the medicinal therapy that makes use of electric current. Since 1855, AC and DC have been in use in commercial and residential establishments as a means to power electric appliances.In these applications, the use of AC power cords are indispensable.

Cords used in AC circuits are either fixed to the appliance or detachable.The detachable power cords are the ones that use a power socket to connect to the appliance rather than the more dangerous power plug, with live pins. Twist-locking features in detachable power cords prevent any end of the cord from being disconnected. These days, there are plenty of power cords for different plugs and sockets that you could find and buy.These power cords include:

What to Know when Getting Hospital Grade Power Cords
• European-made power cords.
• Israeli AC power lines.
• UK-made mains cables.
• Mains cables produced by Switzerland.

There are many mains cables that are each intended and used for a specific appliance, socket and plugs. Because of the diversity, production of cords should follow a standard. Manufacturing of power cords are governed or standardized by the NEMA or the National Electrical Manufacturers Association, an association of entities engaged in the field of electricity. NEMA has authored numerous guides and standards that govern the manufacture of power cords.Aside from NEMA, another standards-setting body for making AC mains cables is the IEC. The IEC has also published standards that are of international scope for the manufacturing of electrical connection receptacles like power cords. To make sure that cords are of high quality, companies should follow the standards set by the IEC and the NEMA. Manufacturing companies should also set high standards in their manufacturing in addition to keeping up with published standards.

One manufacturer of AC power cords that’s worth a mention is SPSD or the Signal and Power Delivery Systems www.signalandpower.com.There are many makers of AC power and mains lines, all of them achieving the standards set by international and country-specific organizations. SPSD, as a maker of power cords, have complied with and been certified by standards organizations in Asia Pacific, North America, Europe, South and Central America, Middle East and Africa.For your AC power cord needs, Signal and Power Delivery Systems offer those at good quality and inexpensive prices.
