description The invention discloses a method of a parallel gap design of composite insulators of a 500-kV power transmission line. The method comprises the following steps: (1), determining a shape of a parallel-gap arcing electrode; (2), determining a material of the parallel-gap arcing electrode; (3), determining an interface of the parallel-gap arcing electrode; (4), determining a geometric dimension of a parallel gap; (5), designing a parallel-gap connection armour clamp; and (6), carrying out parallel-gap electrical performance testing. According to the invention, the method is especially suitable for a parallel gap design of composite insulators of a 500-kV power transmission line, wherein the parallel gap has the advantages of good voltage sharing performance, fast arc-guiding speed, and good protection effect.
