Case Study: SAB Offers Composite VFD Cable for $ Savings for Customer

VFD Cables have many different applications for the following types of Machine Automation:  Lifts, transfers, shuttles, storage/retrieval elevators, feeders, extractors or any application that requires position feedback and external braking.  Customer called our Distributor and described an application to control the velocity, acceleration and position of a device using a VFD with internal/external braking

The current wiring was the Conventional method of running separate cables, one for power and one for motor feedback and motor brake cables, each having an average length of 100 foot. The customer wanted to:  save time in installation/ tear down for shipment to field and reinstallation of the cable.

SAB Solution:

The OEM looked at using our VFD Lean, another cable for braking power and a feedback cable from the manufacturer of the feedback device.  However, through further dialog regarding labor costs, and subsequent design/quote, we were able to convince them to consider one of the following 2 - SAB Composite cable solution for the application:

The first cable would be manufactured with the four motor power conductors along with three 16 AWG shield pairs for internal/external brake power at the motor.

The second one is with the four motor power conductors, two 5 TP position feedback cables and the three shielded 16 AWG pairs for braking.

This application had approximately 20 VFD’s being used with a total length of cable of approximately 7500’.   The analysis for the labor cost to install the cabling using the Conventional method to remove and then reinstall three separate cables vs. SAB’s recommendation of a composite cable, showed SAB’s  composite cable provided the customer with an overall labor and material savings of 3x versus the conventional method.  

Conclusion:

SAB North America can service your needs with our standard product catalog and large inventory in Fairfield.  We also have the expertness to engage our customers in conversation to offer a composite cable if that is the correct cable for the applicationleading to additional savings for customer.
