Do you require VFD (Variable Frequency Drive) cable for on-machine applications, where it will be in constant motion? Or what about needing it for installation in tight spaces?
Up-to-now, these situations have been hard to address. On the one hand, construction-grade VFD and standard THHN building wire or tray cable do not provide adequate VFD system protection or the pliability needed. On the other hand, high performance Belden VFD cable has not had the extreme flexibility needed.
By controlling motors at variable speeds, VFDs save energy and improve process control. However, they also generate electrical noise that radiates out and can disrupt equipment, networks and control systems. Such disruptions can lead to intermittent process variability and even downtime. High performance VFD cable solves the electrical noise problem by having sufficient grounding, insulation, shielding and industrial hardening to protect network and control system infrastructure.
The good news is that high performance AND high flex Belden VFD cable is now available. Let’s review the VFD applications that require very flexible cable and see how our new offerings make installation easier without sacrificing any of the crucial elements needed for high performance.
Some VFD applications, such as the injection molding machinery shown above, have motors mounted directly on the machine and require cable designed for constant motion. Belden’s new Continuous Flex VFD Cable provides both the flexibility and high performance needed.
There are two general categories of VFD applications that require highly flexible cable:
1. Constant Motion Applications
In these VFD applications motors are mounted on machines or robots, such as in automotive manufacturing or on industrial equipment like injection molding machines. These applications require NPFA 79 (National Fire Protection Association) compliance for constant motion. (In Europe a similar standard is IEC 602041.1.)
2. Applications Where Flexible Cable Makes Installation Easier
For these VFD applications, the ability to manipulate the cable is important. Examples include VFDs that are used to:
These situations often require large cables be routed up into tight spaces in cabinets where improved bend radius and flexibility are key for easy installation.
To meet the needs of the applications described above, select VFD cable with:

Selecting and specifying VFD cable is difficult because there are no standards for them. There are many cables on the market today which claim to be VFD cables, many of which do not work well and lead to costly VFD system issues, downtime and even safety issues.
Belden’s new high flex VFD cable is highly engineered to both protect VFD systems from electrical noise and deliver high flexibility for easy installation. Remember, the amount of copper in the cable and proper installation are the two critical components which most directly impact VFD system performance.
Now it’s possible to transmit the power needed to run industrial machine motors for constant motion or tight space applications with very high reliability.
