Whether you’re looking for a new charger for your laptop or a new television for your living room, you’ve likely run across power cords at some point. The three main components of power cords are the plug, the receptacle, and the conductive wire. Each of these components is subject to a number of international standards and regulations, and is manufactured using different materials depending on the application. To make your shopping experience easier, we’ve outlined some of the most common types of cords, including the following.
To ensure safety, you’ll need to know what type of cord you need. While there are standards for the plug and receptacle, each country also has its own requirements for electrical cords. For example, cords in North America must meet the National Electrical Manufacturers Association (NEMA) standards for voltage and current. Besides this, they must also meet the standards for maximum cable temperature and molded plug and female receptacle types. But these regulations do not prevent manufacturers from customizing cord construction. Therefore, it’s important to find out what’s in the power cord before you buy it.
Power cords are usually referred to as mains cables, flexes, or power connectors. These cables are used to provide power to the computer and other devices. The most common types of power cords are PVC-covered. PVC-covered cords are durable and efficient. In addition to the aforementioned types, power cords also transfer alternating current (AC) and direct current (DC).
In the 1950s, manufacturers started making power cords construction string lights with two wires of PVC insulation. Aluminum wire was promoted as a cheap substitute for copper, but it was later found to be harmful due to corrosion. Cloth wire containing asbestos was banned as an insulator. Three-wire PVC insulated cable is currently used in most American households, and is compatible with many power adaptors. They are durable and heat resistant. So, make sure to choose the right cord for your needs.
When shopping for power cords, consider the purpose for which you plan to use them. Usually, power cords are used for domestic and commercial purposes, but they are also used in industrial settings. Industrial settings require higher voltages, which makes them unsuitable for most household applications. Typically, a power cord is 16A to 20A and 125V to 250V. However, when shopping for cords, remember that high-quality power cords will save you money on repair bills and protect you from electrical hazards.
When buying power cords, make sure to choose the correct one based on the region of use. Plug patterns vary between countries and are listed in the Interpower Guide to Worldwide Plug/Socket Patterns. When shopping for power cords from Japan, check the plug pattern and ensure the cord will work in that country. If you are unsure, contact the manufacturer to confirm compatibility. They will likely offer free technical support for their products.
