Selecting Cables for VFD Applications

February 3, 2012

For all their energy savings and process control benefits, variable frequency drive (VFD) systems have a downside too. When these drives fail, they can bring motor-driven industrial processes to a dead stop. To avoid this costly downtime, smart engineers carefully evaluate reliability when configuring a drive system.


All too often, however, the reliability analysis focuses solely on the VFD power electronics and neglects the most vulnerable component in the drive system–the power cable that connects the VFD to the motor. Read more




VFD Cables - Technical Whitepaper

January 25, 2012

Variable frequency drives have an Achilles Heel. Even though the VFD itself is protected against damaging electrical conditions, the drive's power cables can fail when subjected to heat or voltage levels greater than their insulating layers can tolerate. Power cables can also be irreparably damaged by heavy mechanical loads or corrosive environmental conditions.  Fortunately, it is easy to avoid VFD cable failures--and the ensuing downtime--by paying attention to cable design. This technical paper from Lapp outlines the key design features engineers should consider when picking reliable cables for VFD applications. Read more




A New Connector for Harsh Operating Conditions

January 17, 2012

Connectors often have to operate in corrosive, electrically noisy or mechanically challenging environments. Our latest connector housings have been designed to thrive in these environments. Read more




Cable Lab Speeds Product Development

November 1, 2011

When we create new cable technologies, testing has traditionally been one of the biggest bottlenecks in the development process. Even the most minor change to cable materials or structures requires a battery of time consuming tests to ensure compliance with safety standards. Over the past year, we have eliminated that bottleneck by establishing a comprehensive test lab that allows us to perform Underwriters Laboratories (UL) and related tests in our Florham Park facility.

Understand Connector Selection to Avoid Downtime

November 7, 2011

A typical manufacturing plant today will have thousands, or even many thousands, of electrical connections on both fixed equipment and moving machines. And it’s just a matter of time before some of those connections fail or wear out, bringing production machines to a dead stop. One way to minimize this downtime is to “connectorize” power and signal cables. Read more.
