Abstract

The invention provides a high-strength long-rod-shaped insulator and a preparation method thereof, and relates to the technical field of insulators. According to the high-strength long rod-shaped insulator and the preparation method thereof, the high-strength long rod-shaped insulator comprises a long rod-shaped insulator body and an enamel layer on the outer surface of the long rod-shaped insulator body. According to the long-rod-shaped insulator body, the raw materials are matched and coordinated with one another, so that the material has very high strength performance under high pressure, meanwhile, the modified glass fibers are used, the contact effect between the modified glass fibers and the bauxite, the field spar and the Changfeng mud raw materials is stronger, the firing quality of the long-rod-shaped insulator body is guaranteed, and the service life of the long-rod-shaped insulator body is prolonged. According to the present invention, the use strength is effectively ensured, the service life of the insulator is prolonged, the surface of the prepared long rod-shaped insulator body is coated with the glaze layer by using the prepared glaze coating in the atomization spraying manner, and the firing is performed again under the high temperature condition of 400-450 DEG C, such that the prepared finished product long rod-shaped insulator has the high strength.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a high-strength long rod-shaped insulator and a preparation method thereof. Background technique [0002] An insulator is a device installed between conductors of different potentials or between a conductor and a component at ground potential, capable of withstanding voltage and mechanical stress. An insulator is a special insulation control that plays two basic roles in overhead transmission lines: it is used to support and fix the busbar and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the earth. Insulators are used to increase the creepage distance, commonly used are porcelain insulators and fiberglass insulators. [0003] However, the existing insulators have low service strength and short service life. Secondly, the poor quality of the glaze surface is prone to defects such as flower glaze, crystalli...
