BELDEN® EXPANDS ITS LINE OF INDUSTRIAL CABLES FOR VARIABLE-FREQUENCY AC MOTOR DRIVE APPLICATIONS
Richmond, IN – Belden, 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. 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.
Classic Series VFD Cables
Belden's classic line of VFD cables, offered in 16 to 2 AWG, continues to be the highest performing solution in the market. Oversized XLPE insulation provides the lowest capacitance available in a VFD cable and highly effective dual (foil/braid) shielding offers effective EMI low frequency and RFI high frequency noise protection. The cables also include a full-sized insulated green/yellow ground wire, plus they are round and smooth to allow proper sealing of glands and molding applications.
