Abstract

The invention discloses a laminated toughened glass insulator and a preparation method thereof. The insulator is formed with soda-lime glass or ceramic white porcelain glass as the center and externally coated with aluminosilicate glass or low borosilicate glass. The section structure comprises a first and a third layer of aluminosilicate glass or low borosilicate glass; a middle layer of soda-lime glass or ceramic white porcelain glass. A double layer melting furnace is adopted to melt glass raw materials and form glass material base and then a laminated toughened glass insulator is obtained which has a transparent external layer and a blue middle after forming and annealing. The insulator is characterized by more resistance to external impact, no easy occurrence of unfilled corner, fracture and other phenomenon, no generation of cracking, resistance to temperature difference of over 150 DEG C, hard and fine surface without pores, easy self-cleaning, high strength, is bright (like a new one) after long time of outdoor use and has important significance for ensuring the normal operation of electrical power systems.

Description

technical field

[0001] The invention relates to a glass insulator in the field of electrical technology, in particular to a laminated tempered glass insulator and a preparation method thereof. Background technique

[0002] Glass insulators have been widely used in transmission lines due to their good arc resistance and vibration resistance, not easy to aging and good self-cleaning properties. The glass body of glass insulators currently used is made of ordinary tempered glass. The tempering of this glass is tempered by wind, which cannot achieve a uniform tempering effect on the glass, making the glass insulator fragile during the use of transmission lines. , self-explosion and other phenomena, resulting in increased line maintenance costs, increased manpower and material resources, restricting the development and application of glass insulators. Contents of the invention

[0003] The object of the present invention is to provide a laminated tempered glass insulator and i...
