Product Information

Whenever possible, you should use grounded power cords. These cords have an extra wire that helps to ground the appliance in case of a short circuit. This can supply an extra level of safety, so it's worth the extra cost. A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. Power cables that are bundled inside thermoplastic sheathing and that are intended to be run inside a building are known as NM-B (nonmetallic sheathed building cable).

TechMotion 3 in 1 Retractable Magnetic Charging Cable ( Apple Iphone Lightning / USB - C (laptops and chromebooks) / Micro USB )pronged outlets are less common than 3-pronged outlets but can still be found in some older homes and businesses. These outlets only have two holes - one for the hot wire and one for the neutral wire. Because there's no ground wire, power cords that are designed to work with this type of outlet will typically have a two-pronged plug on one end. One of the most common places you'll find power cords is in the home. Virtually any appliance that uses electricity will need a power cord, so it's not uncommon to have several different power cords running through your house. The most common appliances that use power cords in the home include televisions, computers, and lamps. Modern high-voltage cables use polyethylene or other polymers, including XLPE for insulation. They require special techniques for jointing and terminating, see High-voltage cable. Power cords are also available in a variety of different materials, including plastic, rubber, and metal. The material you choose should be based on your specific needs. For example, rubber power cords are a good choice for use in damp or wet areas. For circuits operating at or above 2,000 volts between conductors, a conductive shield should surround the conductor's insulation. This equalizes electrical stress on the cable insulation. This technique was patented by Martin Hochstadter in 1916; [9] the shield is sometimes called a Hochstadter shield. Aside from the semi conductive ("semicon") insulation shield, there will also be a conductor shield. The conductor shield may be semi conductive (usually) or non conducting. The purpose of the conductor shield is similar to the insulation shield: it is a void filler and voltage stress equalizer.

Wayne Beaty, Standard Handbook for Electrical Engineers, Eleventh Edition, McGraw-Hill, New York, 1978, ISBN 0-07-020974-X pg. 18-85 Of course, one of the most important considerations is price. Power cords range in price from dollars to hundreds of dollars, depending on the length, gauge, and material. Be sure to shop around to find the best deal on the power cord you need.

Modern two or three-wire+ground PVC-insulated cable (e.g., NM-B), produced by such brands as Romex® [ citation needed] To drain off stray voltage, a metallic shield will be placed over the "semicon." This shield is intended to "make safe" the cable by pulling the voltage on the outside of the insulation down to zero (or at least under the OSHA limit of 50 volts). This metallic shield can consist of a thin copper tape, concentric drain wires, flat straps, lead sheath, or other designs. The metallic shields of a cable are connected to earth ground at the ends of the cable, and possibly locations along the length if voltage rise during faults would be dangerous. Multi-point grounding is the most common way to ground the cable's shield. Some special applications require shield breaks to limit circulating currents during the normal operations of the circuit. Circuits with shield breaks could be single or multi point grounded. Special engineering situations may require cross bonding. Terrell Croft and Wilford Summers (ed), American Electricans' Handbook, Eleventh Edition, McGraw Hill, New York (1987) ISBN 0-07-013932-6, sections 2-13 through 2-84 One of the most common uses for power cords is with power tools. The power tools, such as drills, saws, and sanders, require a cord to run. The cord supplies the electricity needed to run the tool. Power cords for power tools are typically heavy-duty to withstand regular use and abuse. Surge protector power cords are similar to standard power cords, but with the added benefit of surge protection. They feature a built-in circuit breaker that's designed to trip and cut off the flow of electricity in the event of a power surge. This will protect your appliances from damage caused by sudden spikes in voltage.

Now that you know a little bit more about power cords, it's time to talk about safety. Power cords can be dangerous if they're not used properly, so it's important to be aware of some basic safety tips. As already mentioned, power cords can be used with a broad array of devices. One thing to note though, is that because many of these devices are unique in nature, the power cords they work with are unique to their specific design. The following is a list of common types of inputs power cords can connect to. Liquid or gas filled cables are still employed in distribution and transmission systems today. Cables of 10 kV or higher may be insulated with oil and paper, and are run in a rigid steel pipe, semi-rigid aluminum or lead sheath. For higher voltages the oil may be kept under pressure to prevent formation of voids that would allow partial discharges within the cable insulation. Finally, be sure to follow the manufacturer's instructions when using power cords. These instructions are designed to help keep you safe, so it's important to follow them. Whether you're talking about a monitor power cable or general power cord for PC, there are some commonalities and features many of the best connection cables have in common. The following is a review of the most noteworthy.Another common use for power cords is to connect electronic devices to an outlet. A computer power cable, monitor power cord and TV power cord are all examples of this. As with appliances, most electronics will come with a power cord that's specifically designed for use with that particular device. Power cords exist for one primary reason - to transfer power. They relay energy from point A to point B by way of an electrical circuit. This is made possible by a few key components that are found within the power cord itself. While power cords and extension cords may appear to be similar, they actually serve two very different purposes. Power cords are designed specifically for transferring electricity, while extension cords are intended to extend the reach of an existing power source.
