Belden VFD Cables
These 2,000 V cables for VFDs include classic and symmetrical

designs. The Classic design VFD cables are 14 AWG to 2 AWG with Beldfoil plus

TC Braid Shield. This series of seven cables features oversized XLPE insulation

to provide low capacitance. Highly effective dual shielding provides a low

resistance to ground path, which improves common mode current containment. The

85% braid coverage offers optimum EMI low frequency noise protection, while the

100% 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.

The Symmetrical design VFD cables are large AWG (1 to 4/0),

with a spiral copper tape shield. This series of five cables combines the

benefits of 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% coverage, coupled with improved

flexibility and EMI/RFI noise protection. The three symmetrical bare ground

wires provide a balanced ground system to reduce the likelihood of premature

motor bearing or motor insulation failure.
