Double-hanging-point quadruple strain insulator string for 500kV power transmission line

The utility model discloses a double-hanging-point quadruple strain insulator string for a 500kV power transmission line, which comprises two groups of oppositely arranged duplex strain insulator strings, each group of duplex strain insulator string comprises two insulators, and a duplex plate and a four-eye yoke plate which are arranged at two ends of the insulators and are used for connecting a tower body and a strain clamp to form a duplex insulator string; in the insulator string, the right end of each insulator is sequentially connected with a socket clevis, a four-eye yoke plate, a right-angle clevis, a first PD plate, a PT adjusting plate and a strain clamp, and the left end of each insulator is connected to a two-yoke plate through a ball head suspension loop. The two first PD plates of each group of duplex tension string are fixedly connected to the two ends of the second PD plate respectively; and two ends of the four-eye yoke plate are respectively connected with the socket hanging plates and the r
