VFD cables are shielded cables engineered to work seamlessly with variable frequency drives and the motors they control. They have a number of design features that make them ideal for VFD applications:
- Three power conductors for three-phase power
- Grounding conductor
- Overall metallic braided shield to minimize electrical noise
- Durable and flexible jacket resistant to oils and chemicals
The shielding in a VFD cable is a key component. It helps prevent electrical noise generated by the VFD’s high switching frequencies from interfering with system operation. The shield dissipates this noise safely to ground.
Using properly shielded VFD cables is highly recommended when installing variable frequency drives. The benefits include:
- Flexible Durability – VFD cables are extra flexible to withstand constant motion and vibration. Their jackets resist abrasion, oils, and chemicals for long service life in industrial settings.
- Electrical Noise Reduction – The braided shield provides up to 90% noise reduction versus unshielded cables. This prevents control issues, downtime, and damage.
- Wide Operating Temperatures – Rated for dry temperatures up to 90°C, Variable frequency drive cables ensure stable power delivery in hot environments. Cold-resistant versions are designed for wet or submerged uses down to -40°C.
- Safety – VFD cables meet flammability standards for operation in cable trays and confined spaces. Their voltage ratings are designed to handle VFD voltage spikes.
Properly specified Variable frequency drive cables tailored to the application are critical in VFD systems. They permit longer motor cable runs, minimize downtime risks, and ensure the system operates as intended.
