VFD Cables

AmerCable VFD Cables are specially engineered to provide 100% containment of EMI emissionsand provide longer cable life in VFD applications.

AmerCable VFD cables feature symmetrical insulated ground conductors that reduce inducedvoltage imbalances and carry common modenoise back to the drive.

AmerCable’s high strand count conductors andbraid shield design is much more flexible, easier to install and more resistant to vibration than Type MC cable.

VFD Cables

ApplicationA flexible, braid and foil shielded, 2kV powercable specifically engineered for use in variablefrequency AC motor drive (VFD) applications.

Features� Specially engineered cable design produces

a longer cable life in VFD applications.� Overall braid and foil shield provides 100%

coverage containing VFD EMI emissions.� Symmetrical insulated ground conductors

reduce induced voltage imbalances and carrycommon mode noise back to the drive.

� High strand count conductors and braid shield design is much more flexible, easier to install and more resistant to vibration than Type MC cable.

� Gexol’s lower dielectric constant (standardXLPEs, EPRs and other Type P insulationmaterials have higher dielectric constants)reduces reflected wave peak voltage magnitudes. This allows for longer output cable distances and minimizes the effect of high frequency noise induced into the plant ground system.

� 2kV insulation thickness resists the repetitive2x voltage spikes from 600V VFDs andreduces drive over current trip problems due to cable charging current.

� Dual certified IEEE 1580 Type P and UL 1309/CSA 245 Type X110.

� Highest ampacity ratings: ABS 100˚C, DNV95˚C, LRS 95˚C, Transport Canada 95˚C.

� Severe cold durability: exceeds CSA coldbend/cold impact (-40˚C/-35˚C).

� Flame retardant: IEC 332-3 Category A and IEEE 1202.

� Suitable for use in Class I, Division 1 andZone 1 environments (armored andsheathed).

� Optional braid armor of bronze, aluminum or tinned copper.

Ampacities are based on Table 310.16 of the National Electrical Code (NEC) for conductors rate 90°C, in a multi-conductor cable, at an ambient temperature of30°C. The 75°C column is provided for additional information. The ampacities shownapply to open runs of cable, installation in any approved raceway. Derating for morethan three current carrying conductors within the cable is in accordance with NECTable 310.15 (B) (2) (a). The ampacities shown also apply to cables installed in cabletray in accordance with NEC Section 392.11.

VFD Cables

ApplicationsA flexible, braid and foil shielded,power cable specifically engineered for use in medium voltage variable frequency AC drive (VFD) applications.

Features� Flexible stranded conductors,

braided shields and a braided armor(when armored). Suitable for applications involving repeated flexing and high vibration.

� Small minimum bending radius (6xOD for unarmored cables and8xOD for armored cables) for easy installation.

� Insulation resists the repetitive 3x voltage spikes from VFDs andreduces drive over current trip problems due to cable charging current.

� Overall braid and foil shield provides100% coverage containing VFD EMI emissions.

� Symmetrical insulated ground conductors reduce induced voltageimbalances and carry common mode noise back to the drive.

� High strand count conductors andbraid shield design is much more flexible, easier to install and moreresistant to vibration than Type MC cable.

� Severe cold durability: exceeds CSA cold bend/cold impact (-40˚C/-35˚C).


� Suitable for use in Class I, Division 1, and Zone 1 environments(armored and sheathed).

The circuit of a typical voltage source PWM drive is shown in Figure 1. Each part of the equipment is bonded tothe safety earth system to ensure personnel safety if faults occur.

All parts have capacitance to ground shown by :• CM for the motor windings.• CC1 and CC2 for the power

converter circuits.• CT for the transformer’s secondary

winding to the transformers’ screen.

The IGBT switches are in constant operation at high frequency and this produces an inverter output voltage with a PWM wave shape as shown by the voltage V1(Figure 1).

This IGBT switches also cause a motor line to ground voltage V2 (Figure 1), normally called a common mode voltage.

The common mode voltages cause short high-frequency pulses of commonmode current to flow in the safety earthcircuits, shown by currents I1 and I2 (Figure 1), unless the design includes cable features to stop this from happening.

It is essential that the common mode currents return to the inverter without causing EMC - EMI problems inother equipment, and this means that the common mode currents I1 and I2 must not flow in the safety earthing system.

For the motor, this is achieved by connecting a set of wires from the motor to the inverter that run with the mainpower cables. These are called symmetrical insulated grounding conductors, see Figure 2. These conductorshave a very low impedance compared with the other return path via the safety earthing system.

The three symmetrical insulated grounding conductors and overall shields are connected as shown in Figure 3. This 360° connection is essential.

The common mode currents I1 and I2 now flow in the symmetrical insulated grounding conductors. This happens because the symmetrical insulated grounding conductors are close to the power conductors giving a low impedance route for the currents I1 and I2 compared with the safety earthing system. As I1 and I2 flow near the power conductors this avoids creating external EMC - EMI problems. F I G U R E 3

If symmetrical insulated grounding conductors and an overall EMIshield are not used, EMC - EMI problems are very likely to occur.

For cables used with voltage source PWM drives, a number of features are required to ensure correct operation, avoid overheating and achieve longer service life.

The essential features of a medium voltage cable for PWM drives are :• Insulation designed to withstand the transients produced by the PWM• Insulation with a dielectric constant no greater than 3.0 to minimize capacitance• Voltage rating of 3x the operating voltage to prevent corona• Three symmetrical insulated grounding conductors. Some

cables only have one grounding conductor. This is not acceptableas it produces circulating currents in the earth system

• Extremely fine strands to carry the harmonic currents without overheating (i.e. the inductance of fine stranded conductors is less than 7, 19, 37 strand conductors)

• Overall shield to stop the radiation of voltage EMI fields• Correct termination of the components at both ends• Semiconducting shield around each insulation layer• Metallic layer around each semi-conducting shield to

earth the semi-conducting shield• Correct termination hardware kits to avoid corona failures.
