VFD Cable Description
A variable frequency drive (VFD), also known as an adjustable speed drive (ASD), is a controller that controls a motor or speed by varying the frequency and voltage of a signal.
VFD systems typically generate a lot of electrical noise, such as voltage spikes, reflected waves, charging currents, common-mode voltages, and RFI/EMI interference, which can result in voltages two to three times the supply voltage. Using non-VFD cables can cause insulation breakdown and cable failure, and can also introduce common-mode (or stray) voltages into the VFD motor and equipment grounds, causing motor and equipment failures.
Selecting the right drive cable is critical to reducing noise emissions, voltage reflections, and cable failures. This requires determining the structure that provides the lowest impedance ground path for the application.

VFD Cable Colour Code
- Conductors:
- The main power conductors are typically black, and each is identified with a number (1, 2, 3, etc.) for easy identification.
- Ground:
- The ground wire, or earth conductor, is usually green with a yellow stripe.
- Shield:
- VFD cables often have a shield to minimize electromagnetic interference (EMI). This shield is typically an aluminum foil with a tinned copper braid.
- Jacket:
- The outer jacket of the cable is usually black and made of a material like PVC, which is oil and sunlight resistant.
