The corona discharge of EHV transmission lines in high altitude area is very serious. Based on the Jiantang-Yulong 500kV power transmission project, we using Ansys software to calculate the surface electric field of 500 kV double circuit AC transmission line insulator and fittings. We get the voltage distribution of upper and middle and lower phase insulator string and the surface electric field distribution of fitting. According to the method of standard recommend, we get the corona electric field of fittings in high altitude (4km) are and compared with the result of the calculation. Then, we gives the optimization scheme of equalizing ring is rotated by 90 DEG and diameter increased to 55mm. The results show that the optimization scheme can effectively reduce the maximum electric field strength of the pressure ring and below the corona electric field value of fittings in high altitude.
