Variable frequency drives emit electrical noise, which can interfere with other circuits. This interference can cause motor torque loss or cause motors to stall out or fail completely. It can also reduce system efficiency, pose a hazard to personnel in the area and create false trips of drive overcurrent. To protect those circuits, VFD cable […]

How do you select VFD cables?
Cables used with variable frequency drives (VFDs) need to match the operating environment and other components in the system. Selecting the right VFD cable can help ensure the drive’s reliability and lifecycle. The following are key specifications to consider when selecting a VFD cable. Voltage and ampacity Knowing both the motor and cable’s voltage and […]
Higher standard regarding fire protection in rail vehicles
In order to maintain general safety of passengers, the requirements on cables in rail vehicles have always been very high. The new European Standard DIN EN 45545-2 goes on to increase the requirements regarding fire protection in rail vehicles. Aside from being halogen free, all used cables have to be flame retardant and self – […]
Industrial Ethernet CAT 7 and CAT 7A
Cable requirements for industrial applications can be extremely demanding. They must be able to perform in tough environmental conditions such as higher temperatures, oil and solvents, aggressive chemicals and/or humidity as well as against strong mechanical stress such as flexing in cable chains or twisting in robot applications. Ethernet cables rated for category 5 and […]
