Abstract
This paper reviews a basic data of the surface discharge characteristics for tefton resin in not only pure $N_2$, $N_2:O_2$(80[%]:20[%], I-Air) and $N_2:O_2$(60[%]:40[%]) mixture gas as environment-friendly insulation Gas also $SF_6$. Used electrodes are Knife to Knife. With the changing distance of electrodes and pressure, we can find it, surface discharge voltages and surface dielectric strengths, respectively. Surface discharge Voltages of I-Air are more higher than the other $N_2/O_2$ mixture gases. Moreover, we can obtain that the surface dielectric strengths of $SF_6$ are two times about I-Air, approximately.
