8 AWG 4C Shielded VFD Cable W/ 4 #14 Drain Wires

“8/4 VFD Cable W/ 4 #14 Ground Wires is a heavy-duty, 600V TC-ER / 1000V Flexible Motor Supply rated cable engineered for high-amperage Variable Frequency Drives. Built with XLPE insulation, dual-layer EMI/RFI shielding (aluminum tape and tinned copper braid), and four symmetrical ground wires, it suppresses noise and controls high-voltage spikes. Its rugged, oil-resistant PVC jacket is approved for direct burial, UV exposure, and wet or dry environments.”

Key Features & Benefits: 8/4 Shielded VFD Cable W/ 4 #14 Ground Wires

Standard power wire degrades quickly under high-frequency voltage spikes (reflected wave phenomenon) and radiates severe electrical noise into nearby control lines. This specialized VFD cable eliminates system failures:

• Dual-Layer EMI/RFI Shielding: Combines an aluminum/polyester/aluminum tape shield with an overall 85% tinned copper braid to trap and ground high-frequency noise before it disrupts sensors or PLCs.

• 4 Symmetrical Ground Wires (4x #14 AWG): Features four dedicated tinned copper ground wires balanced within the core, providing significantly better EMI suppression and lower ground impedance than standard single-ground variants during fault conditions.

• Exposed Run (TC-ER) Rated: Complies with UL 1277 for direct-run installation out of the cable tray to the motor without requiring rigid metal conduit, saving substantial material and labor costs.

• Heavy-Duty Industrial Jacket: The oil-resistant PVC outer jacket is rated for direct burial, wet or dry locations (-40C to 90C), and harsh environments exposed to sunlight and chemicals.
