VFD Power Cable

VFD Power Cable
Product description

These are three-conductor Variable Frequency Drive (VFD) cables rated for 600/2000 volts. They feature cross-linked thermosetting polyethylene (XLPE) insulation, three bare grounding conductors—one in each interstice—a corrugated copper shield, and an overall polyvinyl chloride (PVC) jacket. These cables are UL-type TC rated. 

The VFD power cables are designed for use with low-voltage (600 V) AC motors controlled by modern pulse-width-modulated (PWM) inverters. It is essential that these PWM inverters use properly designed power cables to prevent radio-frequency (RF) signals from causing stray electrical noise or motor malfunctions.

 

Design Parameters 

Conductors: Class B, soft drawn, bare copper per ASTM B3 and ASTM B8. 

Insulation: Heat and moisture-resistant, cross-linked thermosetting polyethylene (XLPE) meeting the requirements of UL 44. The insulation is suitable for use in wet or dry locations at a conductor temperature not exceeding 90°C for normal operation. The insulation thickness complies with Table 15.3 of UL 44. Single conductors pass the VW-1 flame test. 

Ground Conductors: Single-conductor cables can be paralleled or multiplexed with up to six conductors to improve installation efficiency. 

Circuit Identification: Appendix E, Method 4 of ICEA S-73-532 (NEMA WC 57). Black conductors with number print: 1-ONE, 2-TWO & 3-THREE 

Assembly: The insulated circuit conductors and three bare grounding conductors are cabled together with non-hygroscopic fillers as needed. The cabled core is wrapped with a binder tape. A corrugated copper shield is applied to the taped core. A PVC jacket is applied to the shielded core. 

Shield: 5 mil thick copper tape (10 mil for 250, 350 and 500 KCMIL versions), corrugated and longitudinally applied with a minimum overlap of 15%. 

Jacket: Heat and moisture-resistant, black polyvinyl chloride (PVC) meeting the requirements of UL 1581. The thickness complies with Table 11.3 of UL 1277.
