[QUOTE="Sidewinder, post: 539324, member: 9512"] SWA is often virtually transparent when it comes to EMC . SY (good SY) is better than SWA wrt EMC, but, you get the other issues already mentioned with SY. I know that some VSD OEMs state that SWA is not suitable for use between drive and motor. You mention 1 VSD & 3 motors, make sure that the drive is ok with this. You also mentioned isolators. The inference is that they are downstream of the VSD, again, this needs to be checked with the VSD OEM. The foil braid stuff is normally CY, though it might be SY. Remember too, if the isolators are acceptable downstream from the drive and they are for routine isolation for mechanical maintenance, for example, they will need to be black/grey, not red/yellow. Red/yellow handled rotary isolators are for emergency stopping/switching/isolation, not routine switching/isolation. [/QUOTE]
