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.
VFD cable prices start at $2.25 per foot (10 or 20 ft. min.)VFD Cable Overview
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
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.
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.
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.
