The utility model 110KV line project duplex improves strain insulator-string by the 3rd angle of outgoing line side yoke plate connecting successively U-shaped link, extending ring and U-shaped link; 3rd angle of described inlet wire side yoke plate connects U-shaped link and strain clamp successively, two insulator strings are connected between two yoke plates, resistance to bracing cable one end clamping cable, derive after other end bending cable, wherein the U-shaped link of outgoing line side to be connected on steel tower on cross-arm, cable is derived from other end bending place after connecting strain clamp one end, another is organized strain clamp bending place that duplex improves strain insulator-string and is connected with being located on cross-arm, this kind of connected mode ensure that the stability that cable connects, and wind resistance, it is comparatively reasonable to design in addition, easy accessibility.
Further, the conveniently connection of length, is also serially connected with length adjustment plate 9 between above-mentioned prolongation ring and U-shaped link, and this length adjustment plate 9 is laid with perforation, and according to the needs of different length, prolongation ring and U-shaped link are connected in the perforation of different spacing.
Further, in order to adapt to different pulling tension requirements, on above-mentioned yoke plate for connect two insulator strings two angles between be provided with several perforation 10, the insulator string at two ends can be connected in the perforation 10 of different spacing.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
