A power cable is a set of one or more insulated conductors that are mainly used for power transmission and distribution purposes. In addition to the conductor, the cables consist of two other main components, i.e., dielectric and sheath. The conductor in the cable provides the direction of the electric current. Insulation or dielectric resists the service voltage. The sheath does not allow moisture to enter and protects the cable from all external influences, such as chemical or electrochemical attacks, fire, etc. The cable may be used in building wiring, electrical equipment, electronic instruments, and any type of application where electric power needs to be transferred.
The type of cable can be divided based on voltage, carrying current, maximum operating temperature, etc.
Based on the application and environment of use, power cables can be as simple as two wire or as complicated as far as material, design, and assembly. Power cables are designed to transfer electrical energy from a power source whether AC or DC to devices like LED modules, PCs, cellphones, televisions, and home appliances to guarantee optimal performance safely and efficiently.
Three-prong AC power cables are commonly used for standard electrical devices. USB power cables are renowned for their versatility in connecting and charging a multitude of portable devices, and DC power cables are essential for devices that operate on direct currents, such as laptops and LED lights. Many kinds of power cables are available, each of which covers specific voltage needs and functions.
Power cables are carefully designed to meet safety regulations and important technical requirements and not only ensure a reliable power supply but also protect devices from potential electrical hazards; also, Special cables, such as power booster cables and surge protector cables, are available that protect devices from power surges, which enhances device functionality and safety. Consumers should pay attention to the types of power cables and their specific applications because this will allow them to make the right choice to make the right connections and increase the life and performance of electronic equipment.
