Beschreibung
Zusammenfassung:The composite cross arm comprises at least one insulator and at least one arcing device connected with the insulator, one end of the at least one insulator is used for being connected with a tower body of a power transmission tower and serves as a low-voltage end, and the other end of the at least one insulator serves as the end, used for hanging a power transmission line, of the composite cross arm and serves as a high-voltage end; each arcing device comprises a high-voltage end arcing assembly and a low-voltage end arcing assembly, the high-voltage end arcing assembly is connected with the high-voltage end of the insulator, the low-voltage end arcing assembly is connected with the low-voltage end of the insulator, and each of the high-voltage end arcing assembly and the low-voltage end arcing assembly comprises an arcing rod; in the at least one arcing device, the electrical gap between the high-voltage end arcing assembly and the low-voltage end arcing assembly of the first arcing device is smaller than th
