I have since done lots of testing on the different manufacturers cables IGUS cables, came out above most others and some where equal in performance, the Cheapest cable per foot that has all the requirements that are needed for VFD Drive use, and works very well is this IGUS CF6-15-04 for 2.2Kw VFD Drive to Spindle cable
There are many things to look at when choosing a cable like this
Diameter of the cable, this can be a big problem if using the spindle connectors plugs that come with these spindles
Flex rating
Amperage Rating
Voltage Rating ( must be a minimum of 600v Rated, higher voltage is better so is the Shield Rating, so sometimes you have to compromise a little to get the ideal cable )
Shield rating
The CF6 shield has a 90% optical and 600v rating Diameter .390" or 10mm cost $1-75 per foot ( The smaller diameter can make the difference to fitting your plug, but a compromise on the voltage Rating )
The CF31 shield has around 90% optical, and 1000v rating Diameter .410" or 10.5mm cost $2-76 per foot ( If it fits your Plug then this is the Best Cable to have )
The CF 896 shield has a 60% optical and a 1000v Rating Diameter .350 or 9mm cost $1-80 per foot ( Low Shield coverage is to much compared to the other ( 2 ) cables here not an Ideal cable for good shielding )
