VFD Cable
Cut-to-Length VFD (Variable Frequency Drive) Cable
- 4-conductor, 16 AWG to 2 AWG
- Foil & Braid Shielding
- 1000V rated for use with 460 volts drives
- Cut to length in 1-foot increments
AutomationDirect / Southwire VFD cable is used to organize and protect the input and motor power wiring for variable frequency drives. It is specially designed to reduce VFD-related interference (EMI) on nearby equipment.
Features
- Cross-linked Polyethylene (XLPE) conductor insulation
- Class K, flexible stranded tinned annealed copper conductors
(per ASTM B33, B172 and B174) - Green ground conductor with yellow stripe, cross linked Polyethylene (XLPE) insulation
- 100% coverage aluminum/mylar/aluminum foil shield
- 85% coverage tinned copper braid shield
- Tinned copper drain wire(s)
- Black Thermoplastic Elastomer (TPE) jacket
- Cut to length in 1-foot increments with low minimum lengths
- Made in USA
VFD cable prices start at $2.20 per foot (10 or 20 ft. min.)
VFD Cable Overview
Why use VFD cable
VFDs generate disruptive electrical noise in the environment around them. The noise emitted can affect other devices such as electronic equipment, commercial grade Ethernet systems and instrumentation wiring. VFD cables combat that by utilizing grounding, shielding & insulation.

4-Conductor VFD Cable
Grounding Configuration and Termination
An improper cable connected to VFDs creates noise-related issues within the system and improperly terminated cables can release captured noise current. AutomationDirect/Southwire VFD cables offer both a ground conductor of equal to the size of the power conductors as well as separate drains for the shielding.
Proper Shielding to Contain Noise
To avoid noise problems, VFD cable needs to be effectively shielded. Research suggests that shielding systems that include a combination foil & braid types are the most appropriate for VFD applications.
Sturdy Insulation for Superior Electrical Performance
Cross-linked polyethylene (XLPE) insulation far surpasses PVC/nylon as an insulator for VFD cables because it can withstand voltages as much as 3x higher.
