Variable Frequency Drives (VFDs) are essential components that control the speed of process equipment. They are used with pumps, blowers, or other motor-driven equipment required to run at variable speeds or loads.
For some industrial projects that use process equipment, a motor’s horsepower requirements can be up to hundreds of horsepower on a 480V power distribution system. Since VFD output cabling provides the connection from the VFD to the process equipment motor, it is good practice to choose a cable that enhances the system’s performance. Selecting the right VFD cable for your project can alleviate some of the common issues VFDs can create.
