Nomex paper (Aramid paper)
YT510,a calendered paper, offers excellent dielectricstrength, mechanical properties, flexibility andresilience. There are 9 thicknesses, from 2 mil to 30 mil (0.05mm to 0.76mm). YT510 is used in almost every known electrical sheet insulation applications. High temperature resistance YT510 can offer short-term overloading.
The typical electrical property values for YT510 paper are shown in Table1. The AC Rapid Rise dielectric strength data of Table1, representing voltage stress levels, withstood immediate at a frequency of 50Hz.
Figure 1 shown temperature effect on dielectric capacity (0.08mm, 3mil). As shown in Figure 1, Temperature has a minor effect on electric properties and resistivity versus.

The effects of moisture (humidity) on the electrical properties of YT510 are shown in Table 2. It shows that it only have minor effect on electrical parameters.
YT510 have compact structure, smooth surface, stable size and excellent mechanical properties. Table 3 is the typical mechanical properties of YT510.
Figure 2 and 3 reflects the temperature and moisture effect on mechanical properties of
YT510 paper. The influence of two factors are similar, like elongation, tear strength and toughness are improved, tensile strength are small decreased. We suggest that the paper should be kept sealed in its protective polyethylene wrapper, to maintain uniform moisture content, until just before use.
