Variable Frequency Drive (VFD) Cable
Using the proper cable when connecting the VFD drive to the motor can significantly influence the reliability of a system. On the other hand, a generic motor supply cable can increase problems and lead to premature failure. Some of these problems include:
- Harmonic Distortion
- Corona Discharge
- Power Distortion
- Electromagnetic Interference (EMI)
- Transients
- High Voltage Spikes
- Standing Waves
- In-rush Current
It is essential to select cable specifically designed for VFD systems. HWC offers high quality VFD cable – both braid and copper tape shielded options.
