Problems solved by technology

Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not have a significant effect and will damage the service and operating life of the entire line
The current blank material of ceramic insulators is mainly made of clay raw materials and barren raw materials. The main disadvantages are that the proportion of clay raw materials and barren raw materials is unreasonable. The product strength margin is small

The clay raw material is prepared from the following components in percentage by weight: 41-77 percent of silicon dioxide, 16-40 percent of aluminum oxide, 1.5-2 percent of ferric oxide, less than or equal to 1.0 percent of calcium oxide, less than or equal to 1.0 percent of magnesium oxide, less than or equal to 3.0 percent of sodium oxide and potassium oxide, less than or equal to 1.5 percent of titanium dioxide and the balance of other impurities; the barren raw material is composed of the following components in percentage by weight: 40-60% of porcelain powder and 40-60% of alumina powder; the process has the advantages of reasonable raw material ratio, few product firing defects, stable ceramic forming performance and high product strength margin.

Description

technical field [0001] The invention belongs to the field of line porcelain insulator production, and specifically discloses a line porcelain insulator blank and a process for producing porcelain insulators from the blank. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. The main function of the insulator is to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical performance requirements are stipulated. If under the specified operating voltage, lightning overvoltage and internal overvoltage, there will be no breakdown or flashover along the surface; unde...
