Hi TN crickets (as to all the noise of underfill and coating)

Our production want send back 10 kilometers of single power cords. Insulator 
is a single layer of Polyolefin. Now, when we crimp or solder these wires, 
the following happens: when bending and gathering wires into bundles for 
strapping and fixing them to chassis, the Polyolefn begins to withdraw from 
the connectors or single contact pin. It creeps a few millimeters and I 
think that won't have any kind of negative impact on  electrical performance 
or reliability or what so everm The amount of withdrawal in our company std 
is set to be maximum one halv of the electrical wire diameterm. I found this 
being a weird requirment, because IPC says 3 times the diameter.

1) So, what do you think, is a little withdrawal of the Polyolefin insulator 
anything to bother about?

2) Do you know of a real good paper describing all about crimping . Molex, 
T&B and some others had, but covers only what makes money.
