“10/4 Shielded VFD Cable is a specialized, 600V TC-ER / 1000V Type Motor Supply rated solution engineered to bridge the gap between Variable Frequency Drives and industrial motors. While standard power cables often fail in demanding VFD environments, this heavy-duty cable utilizes dual-layer shielding (aluminum foil and tinned copper braid) along with moisture-resistant XLPE insulation to suppress EMI/RFI noise, handle high-voltage spikes, and protect motor longevity. Encased in a rugged, direct burial rated PVC jacket, it is built to withstand sunlight, oil, and chemicals in the harshest exposed environments.”

Why Professionals Choose 10/4 Shielded VFD Cable

Standard THHN wire easily fails under high-frequency voltage spikes (reflected wave phenomenon) and bleeds electrical noise into nearby control circuits. This VFD cable is engineered to eliminate these failures entirely:

• Advanced EMI/RFI Shielding: Combines a high-performance aluminum polyester foil shield with an 85% tinned copper braid to trap and ground high-frequency noise before it reaches your PLCs or sensors.

• 4-Conductor Redundancy: Features a dedicated, tinned copper ground path that is significantly more effective than standard 3-conductor variants at reducing EMI in the event of system component failures.

• Exposed Run (TC-ER) Rated: Complies with UL 1277 for direct-run installation from tray to motor, completely eliminating the high labor and material costs of installing rigid conduit.

• Extreme Durability: The heavy-duty PVC outer jacket is built for direct burial, wet environments, and areas exposed to harsh industrial chemicals, oil, and continuous UV sunlight.
