Electrical characteristic of tracking resistance, volume resistance, insulation breaking strength etc. and mechanical characteristic are required to high voltage insulation insulator silicone rubber. Tracking resistance is adding much ATH to improve tracking resistance as the most important factor among them. But, there is problem that mechanical strength grows worse rapidly adding much ATH. Therefore, this research studied effect that flame retardant gets to tracking resistance during factor that influence to tracking resistance.

In this study, we have come to the following conclusions regarding to the electrification properties (electrostatic electrification voltage and electrification relaxation time) of electrostatics in the three type of specimen (size: $4cm{\times}4cm{\times}0.103cm$) of silicone rubber which is mixed with the ATH (Aluminium Trihydrate(Al($OH_3$)) of 30 phr, 60 phr, 120 phr as reinforcing filler. The electrification properties of electrostatics were measured for the different mixing ratio of ATH with the applied voltage of DC 10 kV at the temperature range of $10^{\circ}C{\sim}30^{\circ}C$ and humidity range of 60%~80%. When the temperature remained constant, the electrical resistance decreased as the humidity increasing in the range of 60%, 70%, 80%. In contrast, when the humidity remained constant, the electrical resistance increased as the temperature increasing in the range of $10^{\circ}C$, $20^{\circ}C$, $30^{\circ}C$. Regarding these results, may be it is because the absorption of O-H molecule appeared in the silicone specimen. It was confirmed that when the temperature remained constant, the electrification relaxation time decreased as the humidity increased. In contrast, when the humidity remained constant, the electrification relaxation time increased as the temperature increased.
