Abstract

The invention relates to a high-intensity direct current electrical porcelain formula, which is prepared from the following substances in parts by mass: 25 to 30 parts of Dongshengtu, 20 to 26 parts of Jingyangtu, 22 to 28 parts of low-titanium alumina, 6 to 10 parts of Jiangjintu clay, 1.5 to 3 parts of barium carbonate and 12 to 18 parts of alpha-Al2O3. The performance of the high-intensity direct current electrical porcelain formula completely reaches the formula design requirement and the product performance requirements; the current production process can be met; the drying bending intensity is higher than or equal to 5.0MPa; the porcelain bending intensity is higher than or equal to 150 MPa; the glazing bending intensity is higher than or equal to 200 MPa.

Description

technical field [0001] The invention relates to the technical field of electric porcelain insulators, in particular to a formula of high-strength direct current electric porcelain. Background technique [0002] Electric porcelain is a component used in power systems that mainly supports and insulates, and sometimes also serves as a container for other electrical components. Therefore, there are higher requirements for its mechanical properties, electrical properties, and environmental resistance (hot and cold, anti-pollution, aging, etc.). [0003] Electrical ceramics are referred to as electric porcelain. Broadly speaking, electric porcelain covers a variety of electrical ceramic products, including insulating ceramics, semiconductor ceramics and so on. Electric porcelain is an important basic device in the electric power industry. Electric porcelain is mainly used in transmission lines, substations, electrical equipment of various voltage levels in power systems, and in ...
