Provided by the utility model is a dual-hanging point dual-cable clamp duplex V-shaped combination insulator chain for a +/-500-kV same-power double-circuit line. In other words, the utility model relates to an insulator suspension chain on a high-capacity power transmission line; and the spatial combination and connection of four-divided yoke plates and insulator chains is used to meet the requirement of an eight-divided conductor. The provided insulator chain comprises two groups of V-shaped suspension insulation chains. Each group of the suspension insulation chains includes two insulation chain bodies in parallel connection; one end of each insulator chain body in each group of the suspension insulation chains is successively connected with a U-shaped suspension ring, a DB type adjusting plate, a U-shaped suspension ring and an EB hanging point metal fitting; and the other end thereof is connected with a same LF yoke plate by an U-shaped suspension ring. And each LF yoke plate is respectively with two four-divided suspension yoke plates in parallel by two right-angle suspension plates; and grading rings are installed on the LF yoke plates. Besides, suspension cable clamps are installed on all the four-divided suspension yoke plates. According to the utility model, the requirements of the strength and the stability of the +/-500-kV power transmission lines can be met; and security and reliability of the operation on various conditions can be realized.
