From the aforementioned comparisons, it can be concluded that the dimensional accuracies of the undried parts treated by route II are the highest for the peripheral dimensions and the diameter of the central hole. Nevertheless, its corresponding dried part can also basically meet the accuracy requirements. But in the usage of the plate, moisture should be prohibited to ensure its insulating and antibreakdown properties; hence, re-drying after the boiling water bath is recommended. 4.2 Mechanical property improvements of the plate treated by the three routes From the comparison and analysis of the three routes, it can be concluded that the re-dried plate treated by route II is preferred for ensuring the dimensional accuracies, mechanical properties, and the employment character of the medium voltage environment. 5 Conclusion The structural characterization of the plates (untreated and treated by the three routes) were carried out by X-ray diffraction (XRD, D/max-2500/PC, Japan). Data were collected over the range 2 θ = 10–40° in the fixed time mode with a step interval of 0.02.

Performing measurements using a micrometer showed that the dimensional accuracies were improved after the three treatment routes; however, there exist some nonnegligible differences between the accuracies obtained with the three routes. 4.1.1 Dimensional accuracy of the central hole Amorphous and crystalline phase interaction during the Brill transition in nylon 66.
