high voltage on flat ribbon cables?

voltage signals between two circuit boards. The max voltage is about 300 to 400 volts, and current flow is just microamps. We have been using 50-pin flat ribbon cables with 0.050" pitch for breadboarding, but are looking for a product-compatible solution. Two ribbon cable manufacturers (3M and TE) spec this type of cable for 300V in USA, but

Thanks for the link and info. I'm still not sure how to find the answer th ough. Do you know anyone who knows how to navigate these specs? Perhaps t he safety testing companies? -Lou

Talk to CJ Wire and Cable; these guys actually make cable to order and so know the stuff. I have in hand EE24(19) 1000V 200C - RED (and - BLACK) which indicates to me that your requirement should not be out of line.

The actual insulation thickness requirement for the application (functional voltage and safety isolation) will be listed in the relevent IEC safety standard that you're addressing: functional insulation between adjacent conductors, or safety insulation between conductors and the external environment.

The standard for the cable type itself merely describes dimensions and materials relevent to their manufacturing and inspection, for the listed uses. Any similar standard, produced by an accredited source would be considered suitable, if it accurately describes the materials being used, in an IEC document package for CE.

Safe insulation barriers may be constructed, independent of the cable itself, by adding layers of reognized and appropriate material to meet the requirements of the safety standard.

High voltage energy-limited circuits may also be considered 'safe' if there's no stored energy delivered during single-fault contact, or residual current in excess of stated limits, depending on the specific standard.

So the safety standard is the place to look first, before determining cabling requirements.

Talk to Bill Thune of CJ Wire and Cable; he is an expert on custom and semi-custom stuff.
