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.
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. 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. 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. 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. Power cords enable all the devices we rely upon daily basis, as it plays a massive role in our lives. It's important to have a few good quality power cords on hand to keep your devices running smoothly. Here, we'll take a look at surge protectors, extension cords, and all types of line cord switch - all of which can be used to help you get the most out of your devices.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. The most common type of outlet you'll find in both domestic and commercial settings is the 3-pronged outlet. This outlet features three holes - one for the hot wire, one for the neutral wire, and one for the ground wire. Power cords that are designed to work with this type of outlet will typically have a three-pronged plug on one end. 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 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. A hybrid cable can include conductors for control signals or may also include optical fibers for data.
Liquid filled cables are known for extremely long service lives with little to no outages. Unfortunately, oil leaks into soil and bodies of water are of grave concern and maintaining a fleet of the needed pumping stations is a drain on the O+M budget of most power utilities. Pipe type cables are often converted to solid insulation circuit at the end of their service life despite a shorter expected service life. Cables for direct burial or for exposed installations may also include metal armor in the form of wires spiraled around the cable, or a corrugated tape wrapped around it. The armor may be made of steel or aluminum, and although connected to earth ground is not intended to carry current during normal operation. Electrical power cables are sometimes installed in raceways, including electrical conduit and cable trays, which may contain one or more conductors. When it is intended to be used inside a building, nonmetallic sheathed building cable (NM-B) consists of two or more wire conductors (plus a grounding conductor) enclosed inside a thermoplastic insulation sheath that is heat-resistant. It has advantages over armored building cable because it is lighter, easier to handle, and its sheathing is easier to work with. [8] Modern power cables come in a variety of sizes, materials, and types, each particularly adapted to its uses. [6] Large single insulated conductors are also sometimes called power cables in the industry. [7] 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.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. Mass-impregnated paper-insulated medium voltage cables were commercially practical by 1895. During World War II several varieties of synthetic rubber and polyethylene insulation were applied to cables. [3] 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.
The first power distribution system developed by Thomas Edison in 1882 in New York City used copper rods, wrapped in jute and placed in rigid pipes filled with a bituminous compound. [1] Although vulcanized rubber had been patented by Charles Goodyear in 1844, it was not applied to cable insulation until the 1880s, when it was used for lighting circuits. [2] Rubber-insulated cable was used for 11,000-volt circuits in 1897 installed for the Niagara Falls power project. In essence, a power cord can be useful anywhere you have a place to plug it in. However, there are specific applications where they really shine. The following are the most common uses for power cords. Armored cable, known by the genericized trademark "BX" - flexible steel sheath with two cloth-covered, rubber-insulated conductors [4] - introduced in 1906 but more expensive than open single conductors Asbestos was used as an Insulator (electricity) in some cloth wires from the 1920s to 1970s, but discontinued due to its health risk.Another amazing advantage of high-quality power cords is flexible construction. This means the cord is made from materials that allow it to be bent and twisted without damaging the internal wires. This can be helpful in multiple situations, such as when you need to route the cord around obstacles. Though we may not always think about them, power cords are essential to our way of life. By following the tips above, you can be sure to use them safely and effectively. Modern two or three-wire+ground PVC-insulated cable (e.g., NM-B), produced by such brands as Romex® [ citation needed]
