October 16, 2009 -- Belden announced the addition of new 2000-Volt VFD cable designs to its existing line of Variable Frequency AC motor drive cables.
Variable Frequency Drives (VFDs) regulate the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power they deliver to the motor. Belden maintains that these drives are becoming prevalent in a wide range of industrial applications since they offer multiple benefits, including the ability to save substantial amounts of energy during motor operation, making them an attractive and economical "green" solution.
The new 2000V VFD Cable designs added to Belden's line include:
-- Classic design VFD cables, 14 to 2 AWG, with Beldfoil plus TC braid shield: Similar to Belden's other VFD cables, this series of seven cables features oversized XLPE insulation to provide the lowest capacitance available in a VFD cable. Highly effective dual shielding provides the lowest resistance to ground path, which improves common mode current containment. The 85 percent braid coverage offers optimum EMI low frequency noise protection, while the 100 percent aluminum/Mylar tape shield offers RFI high frequency noise protection. Also included in the smooth, round cables are full-size, insulated green ground wires with a yellow stripe and drain wires for ease of installation and termination.
-- Symmetrical design, large AWG (1 to 4/0), with spiral copper tape shield: Similar to Belden's other symmetrical cables, this series of five cables combines the benefits of Belden's classic VFD cables with additional features for use on larger, more powerful AC motor drives. Highly effective shielding provides a low resistance ground path, which improves common mode current containment. Spirally applied dual copper tape shields provide 100 percent coverage, coupled with improved flexibility and EMI/RFI noise protection. Three symmetrical bare ground wires provide a balanced ground system to reduce the likelihood of premature motor bearing or motor insulation failure.
All of Belden's new 2000V UL 1277 Type TC-ER cables are UL rated for direct burial, feature black sunlight- and oil-resistant PVC jackets, and meet all applicable industry standards and specifications for VFD cables.
