VFD Cable

VFD Cable

Product Description

The VFD Cable is a specialized cable engineered specifically for use with Variable Frequency Drives (VFDs) to power electric motors in industrial automation systems. Unlike standard power cables, it is designed to withstand the unique challenges posed by VFDs, which output high-frequency Pulse Width Modulated (PWM) signals. These signals can cause voltage spikes, reflected wave phenomena, and significant electromagnetic interference (EMI). The cable's construction typically features symmetrical, parallel cabled conductors to minimize inductive imbalance, specialized insulation resistant to partial discharge, and robust multi-layer shielding—often a combination of a drain wire, aluminum foil, and a tinned copper braid. This design ensures reliable motor operation, protects against premature insulation failure, and contains EMI to prevent disruption to sensitive nearby equipment.

Ideal for harsh industrial environments like manufacturing plants, processing facilities, and HVAC systems, the VFD Cable enhances system longevity and reduces downtime. Its advanced shielding effectiveness suppresses both radiated and conducted noise, ensuring compliance with EMC regulations. The cable is built for durability, with oil-resistant and flexible jackets that can withstand mechanical stress, temperature variations, and exposure to chemicals. By providing a clean power transmission path from the drive to the motor, it is an essential component for maximizing the performance and lifespan of the entire variable speed drive system.
