Abstract

The invention discloses a high-strength column type electric porcelain insulator for a high-voltage line and a manufacturing process of the high-strength column type electric porcelain insulator, and belongs to the field of insulators, the high-strength column type electric porcelain insulator comprises a porcelain body and a metal accessory, an adhesive layer is arranged between the metal accessory and the porcelain body, and the adhesive layer comprises the following raw materials in parts by weight: 50-90 parts of an inorganic cementing material and 1-20 parts of an elastomer, wherein the inorganic cementing material contains a nano oxide, a pore passage is formed in the elastomer, and the nano oxide is adsorbed in the pore passage. According to the invention, the elastomer is added into the inorganic cementing material, so that on one hand, the cementing strength of the inorganic cementing material can be enhanced, cracks are prevented from being generated after use, and the service life is prolonged; on the other hand, due to the excellent elastic performance of the elastomer, stress relaxation generated after the gel layer is used for a long time can be reduced, and the loosening phenomenon of the porcelain body and the metal accessory after long-time use is avoided.

Description

technical field [0001] The invention relates to the field of insulators, in particular to a high-strength column-type electric porcelain insulator for high-voltage lines and a manufacturing process thereof. Background technique [0002] Electric porcelain insulators for high-voltage lines are a special insulation control that can play an important role in overhead transmission lines.
