Zusammenfassung:The 800kV flexible direct-current wall bushing comprises a capacitor core in the bushing, a current-carrying conductor, an outdoor composite insulator, an indoor composite insulator, a first flange, an indoor end structure, an outdoor end structure and a grading ring. The capacitor core is coated outside the aluminum rolled pipe and forms an asymmetric structure by taking the first flange as an axis, and the length of the outdoor side capacitor core is longer than that of the indoor side capacitor core; the current-carrying conductor is arranged along the capacitor core in the sleeve and the axes of the outdoor composite insulator and the indoor composite insulator, and a voltage-sharing device is arranged at the contact position of the current-carrying conductor and the aluminum coiled tube; the outdoor composite insulator and the indoor composite insulator are installed on the two sides of the first flange and form a complete closed air chamber together with the indoor end structure and the outdoor end stru
