The Anatomy of VFD Cables: Breaking Down Every Benefit

Variable Frequency Drive (VFD) cables require robust quality materials that can withstand harsh industrial environments. We’re going to take a deep dive into each component of our 2KV VFD cables and how these materials make all the difference.

EMI Shield

The electromagnetic interference shield (EMI Shield) is the first layer of defense for the rest of your VFD cable. The EMI shield’s main purpose is to block electrical noise from interfering or damaging nearby sensitive equipment. Our EMI shield is constructed from 5 mil copper tape with a minimum overlap of 50%, ensuring complete coverage and protection.

Symmetrical Ground System

Constructed in a symmetrical pattern, the ground system is crucial for providing a consistent performance. This is done through the 3 bare copper wires that are arranged around the phase conductors to block any electrical noise. By wrapping the bare copper in a symmetrical pattern, it balances the electrical operation of your application and boosts overall safety.

Special Phase Conductor Insulation

The phase conductor insulation is the most robust form of protection within the VFD cable. The insulation is created from XLPE, a heavy-duty material that can handle rapid voltage changes and prevent fire threats. This insulation is able to withstand high temperatures up to 90°C and a VW-1 rating of flame resistance, extending your cable life and ensures reliable power delivery.

The Bottom Line

Combining all three components ensures your electrical system is protected with the highest quality materials and will last. To hear more about our VFD cables and that are NFPA 79 compliant, contact Cameron Connects Industrial Team, at 501-850-0096.
