Abstract: This study practiced a simulation experiment for discharge phenomenon and electric field intensity of basin insulators to improve their insulating ability. It also researched the influence of creep-age distance on the basin-type insulator and optimized its quality. The new basin-type insulator can balance the insulation ability of both sides. This paper proposed to include the ability of creep-age synthesized electric-field strength into the insulation to assessment. The result of the experiment shows that the improved product has better insulation ability.
Key words: basin insulator; insulation design; lightning impulse voltage
