VFD or EMC cables have been specially designed for use in installations where it is necessary to limit the effects of Electromagnetic Interference (EMI), also know as Radio Frequency Interference (RFI).

The new generation of variable-speed drives provide a series of advantages to their users. However, there are also some disadvantages to them. One of their main problems is that of EMI or Electro-Magnetic Interference. This can cause problems in the motor if not dealt with correctly. In order to limit the extent of EMI it is necessary to use the right equipment and a cable with EMC, or Electro-Magnetic Compatibility.

With regards to cable the necessary EMC is achieved by firstly ensuring a symmetrical distribution of the conductors. This is achieved by spliting and reducing the earth conductor to fit snuggly into the gaps between the conductors. Secondly, a special pro...
