Offered in 5 sizes from 1-4/0 AWG, Large AWG Symmetrical VFD cables feature 3 stranded XLPE TC circuit conductors, 2 spiral copper tape shields for flexibility and EMI/RFI noise protection, and 3 symmetrical bare copper ground wires. Signal Pair VFD Brake Cables, comprised of 16-8 AWG VFD cables, feature 3 stranded XLPE TC circuit conductors, full size insulated green/yellow ground wire, dual (foil/braid) shield for EMI/RFI noise reduction, and signal pair for brake.

RICHMOND, IN - Belden CDT Electronics Division, a world leader in the development of specialty cable products for the industrial, commercial, broadcast and residential markets, announces the expansion of its line of Variable Frequency Drive (VFD) cables for industrial AC motor drive applications. Line additions include five Large AWG Symmetrical VFD cables and five new Signal Brake Pair VFD cables. The new cables supplement Belden's classic line of 16 to 2 AWG flexible VFD cables.

In industrial settings, VFD cables are used to carry power from AC drive systems to AC motors. In doing so, they are subjected to the high power levels of pulse-width modulated (PWM) signals, and also to extreme voltage. Voltage extremes can lead to a corona discharge between the cable's conductors, damaging not only the cabling, but the motors, bearings, drives and related equipment. This can result in drive failure and costly production downtime. Conventional VFD cabling solutions, such as armored cable and lead wire conduit, are cumbersome and difficult to install and do not solve noise and corona discharge problems. Belden's full line of VFD cables were designed and engineered to overcome these challenges.

The Belden series of VFD cables now includes:

- Large AWG VFD Cable with Symmetrical Design. The new 1 to 4/0 AWG cables feature three stranded XLPE TC circuit conductors and two spiral copper tape shields that improve flexibility and EMI/RFI noise protection. Three symmetrical bare copper ground wires provide a balance ground system to reduce AC motor shaft voltage, which reduces the likelihood of premature motor bearing or insulation failure. The large VFD cables are designed for use on larger, more powerful AC motor drives.
