Pulsed electric strength of polypropylene film

Аннотация

We have reported on the results of experiments on electric strength of a 2-μm-thick polypropylene film under pulsed loading of samples in the submicrosecond and microsecond time intervals. It has been shown that experimental data on the pulsed breakdown of the polymer film can be described using the concept of the ionization mechanism of breakdown of polymers, which is not associated with the development of impact ionization of molecules in them.
