Composite insulator

The composite insulator comprises an upper fitting, a lower fitting, an umbrella skirt, a glass fiber core rod and a sheath, a bird repelling mechanism is arranged between the umbrella skirt at the top of the glass fiber core rod and the upper fitting, and the bird repelling mechanism comprises a first insulating sleeve, a blade plate and a wind chime; the glass fiber core rod is rotatably sleeved with the first insulation sleeve, a limiting flange is fixedly arranged on the portion, below the first insulation sleeve, of the glass fiber core rod, two insulation rods horizontally extending out are symmetrically arranged on the side wall of the first insulation sleeve, and the two blade plates are obliquely and fixedly connected to the outer ends of the two insulators respectively; and the wind chime is arranged in the middle of the insulating rod 302. According to the utility model, the glass fiber core rod sheath of the composite insulator can be prevented from being pecked by birds, and birds near the compos
