The compression protrusions 740 and 840, the adhesive injection holes 750 and 850 drilled on the upper surfaces of the sleeves 720 and 820 to communicate with the inside, and the adhesive drilled on the upper surfaces of the sleeves 720 and 820 to communicate with the inside. Including the confirmation hole (760, 860), the inside of the sleeve (720, 820), the main line portion (331, 431), and the adhesive (770, 870) that is injected and cured between the bent portion (332, 432), a plurality of The two crimping protrusions 740 and 840 are press-fitted into the coating of the extra-high voltage distribution line 330 and the commercial voltage distribution line 430, and the inner circumferential surface of the sleeve 720 and 820 and the extra-high voltage distribution line 330 and the commercial voltage distribution line 430. The extra-high voltage distribution line 330 and the commercial voltage distribution line 430 are solid by the adhesives 770 and 870 injected into the space between the outer circumferential surfaces of the main wire parts 331 and 431 and the bent parts 332 and 432 of the ) and cured. are conjoined,
When the adhesives 770 and 870 are injected into the adhesive injection holes 750 and 850, the internal air is discharged through the adhesive checking holes 760 and 860, so that the adhesives 770 and 870 are smoothly injected and the adhesive When the (770, 870) is fully charged, the adhesive (770, 870) flows out through the adhesive confirmation hole (760, 860) to connect to the transformer, characterized in that it is configured to perform accurate work regardless of the operator's skill level. Telegraph pole insulator fixing system of power distribution line.
