Save energy, protect your motors and simplify your setup

Keep your motors running clean and smart 

Energy savings and equipment longevity might not sound like they come down to your choice of cable, but with Variable Frequency Drive (VFD) cables, that’s exactly what’s at stake.

VFD cables are built to handle high-frequency voltages and reduce interference between your motor and drive. That makes them essential for anyone looking to keep systems efficient, protected and future-proofed.

Whether you’re spec'ing out a new panel, upgrading a production line or managing motor loads across multiple machines, we’ve got you covered with the right VFD solutions – and the accessories to match.

Why use VFD cables?

If you’re running motors on a VFD, standard power cables won’t cut it; you’re opening the door to:

• Voltage spikes

• Electrical noise

• Motor overheating

• Downtime from premature failure

VFD cables are engineered to prevent those problems by:

• Minimizing voltage reflection at the motor

• Controlling high-frequency electrical noise

• Improving EMI/RFI performance across long runs

• Protecting motor insulation and bearings from damage

Check out the difference VFD cables make; Steve Wetzel, one of the Principal Application Engineers at Southwire, compared two motors – one using standard wire, the other with VFD and the difference was immense:

Southwire & Lake Cable = Trusted Performance

We partner with Southwire and Lake Cable to bring you top-quality VFD options that work as hard as you do. Whether you need something ultra-flexible for a tight space or tough enough for direct burial, we’ve got options that match your install environment and compliance requirements.

Our selection includes:

• Flexible or non-flexible builds
• Multiple ground configurations
• Multiple voltage and insulation types, all up to code
• Options for conduit, tray, trough, aerial and direct burial installations

And it’s not just about cable, we help you get it installed right too.

We Don’t Stop at the Spool

If you’ve worked with VFD before, you know it’s not just a matter of pulling wire and walking away.

Shielding only works if it’s properly terminated. Bonding only protects if it’s grounded correctly. That’s why we offer more than just the cable, we make sure you have everything you need to do it right.

We help you source the right:

• Bonding and grounding elements
• Termination kits
• Shield connectors
• Conduit fittings and strain reliefs

Skip any of these and you risk turning a clean system into a ticking time bomb. Don’t let poor accessories undo an otherwise solid setup.

Why Capital Electric?

Because we know the difference between just selling wire and building solutions.

Here’s what you can expect:

• Technical support to get you exactly what you need
• Vendor relationships for answers fast
• Accessory sourcing to complete your install
• Custom solutions when off-the-shelf won’t cut it
