VFD Cables support large horsepower motors.

Press Release Summary:

Available in 250 MCM, 350 MCM, and 500 MCM sizes, Variable Frequency Drive Cables support installations of up to 250 hp motors at 460 V. Units are designed with symmetric bare grounds, dual copper tape shield, XLP insulation, and industrial-grade PVC jackets. For max safety, cables help protect system against damage from reflected wave voltages and capacitively coupled current. VFD cables are rated for use in exposed-run cable trays, direct burial, and wet or dry conditions.

Original Press Release:

Belden Introduces MCM VFD Cables to Support Large Horsepower Motors

St. Louis, Missouri - Belden (NYSE:BDC), a global leader in signal transmission solutions for mission-critical applications, announces the extension of its proven line of variable frequency drive (VFD) cables to include 250 MCM, 350 MCM and 500 MCM sizes. MCM VFD cables support installations of up to 250 horsepower motors at 460V for use in oil & gas, petrochemical, power generation, water/wastewater treatment and other demanding industrial environments.

Belden MCM VFD cables are rated for use in exposed-run cable trays, direct burial and in wet or dry conditions. Belden's MCM VFD cables are designed to provide superior performance in noise-sensitive applications or in any damp or wet environment where reflected wave voltages may degrade PVC/nylon conductors. The cable is suitable for use with virtually all variable frequency drives, as well as for use as shielded power cable for other solid-state devices.

Superior Electrical Performance and Reliability for VFD Applications

VFDs reduce facility energy consumption and thus operating costs; however, VFDs can be a significant source of noise, most particularly electromagnetic interface (EMI), in a facility. In addition, VFDs are usually operated in close proximity to sensitive instruments, critical networks and safety systems. Proper cable selection from cables specifically designed to connect to VFDs can mitigate adverse effects on nearby cable systems and reduce the likelihood of cable or motor failure.

Belden's MCM VFD cables are designed to provide superior common mode current protection. They help protect a system against damage from reflected wave voltages and capacitively coupled current for maximum safety and reliability. Design features of Belden MCM VFD cables include symmetric bare grounds, dual copper tape shield, enhanced XLP insulation, industrial-grade PVC jackets for longer life and a TC-ER (Exposed Run) rating that allows cable to run from cable tray to point of utilization per the NEC to reduce the need for additional support or protection.


Belden's MCM VFD cable carries the following ratings: 2000V UL 1277 Type TC-ER per 2005 NEC Article 336, 1000V CSA TC C22.2 No 230, 90°C wet/dry, Class I & II, Div. 2 hazardous locations, UL 1685 vertical tray flame test, FT4, IEEE 1202 vertical tray flame test at 70,000 BTU/hour. The cable is rated UL direct burial, oil and sunlight resistant, RoHS compliant and CE approved.

Part of a Large Family of Belden VFD Cables

Belden offers a wide range of VFD cable gauges, giving drive manufacturers the most options possible for specifying the appropriate sizes for their specific applications.
