Abstract
The utility model discloses an insulating rod for a power line. The insulating rod is provided with a hollow composite cylinder (1), wherein a layer of glass fiber core rod (2) forms an annular section, and the hollow composite cylinder (1) is integrally connected through epoxy resin curing. The insulating rod is characterized in that: a dense filling core (4) is arranged in the hollow composite cylinder. Through the utility model, the insulating rod with the structure can be used as a post insulator of a light low-grade power transmission and transformation line as well as a skeleton of a post insulator of a high voltage grade. Moreover, the insulating rod also can be used as a power line pole of a low-voltage grade power transmission and transformation line to be applied to a power transmission and transformation line; and the insulating rod has obvious characteristics of tension resistance, oil stain resistance, bending resistance and the like. Due to action of the middle filling core, the insulating rod has higher strength and rigidity and good bending resistance.
