Hi All.
Seems lately when I post as question, I post the most difficult ones as they not only stump me... but seemingly others. Good fodder for someones PhD dissertation perhaps? Here is another.
I have a braided copper cable with a PVC insulation that is used HEAVILY by an operator. Because the electronics attached to this device is a mission critical part, I want to ensure the insulation is extruded in such a manner that it maintains a DURABLE mechanical bond to the copper braid. This bond then ensures that the load path for axial and torsional stresses are carried by BOTH the braid AND the insulator as a composite, not two individual materials. This helps the cable to transfer a torsional load across the length of the cable, and not in a localized area (resulting in wire and braid fatigue).
With that said, is there some ASTM or JEDEC specification or other (unbenounced to me obviously) that would enable me to place a control on a print to ensure the cable is made in the above manner? OR, are there some inspection methods or plans anyone has come across for such a part?
Thanks for taking time to read and perhaps provide some feedback on this.
