Abstract
The invention discloses a composite insulator triple Y-shaped overhung string. The composite insulator triple Y-shaped overhung string comprises two composite insulator branch strings, a composite insulator main string and an eightfold split overhung yoke plate. The two composite insulator branch strings form a V shape and are both connected with the composite insulator main string through cross yoke plates. The bottom of the composite insulator main string is connected with the eightfold split overhung yoke plate. The Y-shaped structural design is adopted, stability is high, the requirement for towers is low, and the cost of towers is reduced; the composite insulator branch string and the composite insulator branch main string are respectively provided with three composite insulators, and the insulating performance is good; the double-wire-clip structure is adopted, the stability of hardware fittings is enhanced, and the composite insulator triple Y-shaped overhung string can be used for places with the long span or the high fall.
