4 Wire
4 wire is a term used in electrical engineering and refers to a type of electrical cable that has four individual conductors or wires within it. This type of cable is commonly used in applications that require a higher level of precision or accuracy, such as in communication systems, industrial control systems, and power transmission applications. The four wires within the cable are typically used for transmitting signals or power, and are often shielded to minimize interference and ensure reliable performance. The use of 4 wire cable has become increasingly popular in recent years due to its ability to provide better performance and reliability in a wide range of applications.
