【Introduction to Electric Porcelain】

Electrical ceramics is referred to as electrical porcelain. Refers to a porcelain electrical insulating material with good insulation and mechanical strength, such as insulators. Electroceramics are used in power systems to mainly support and insulate components, and sometimes also serve as containers for other electrical components. Therefore, it has higher requirements for its mechanical properties, electrical properties, and environmental resistance (cold and heat, anti-pollution, aging, etc.).

Electric porcelain is an important basic device of the electric power industry. The electric porcelain manufacturing industry belongs to the field of equipment manufacturing that is supported by the country during the "Eleventh Five-Year Plan" period, and is the basic industry of the national economy. Electric porcelain mainly includes other ceramics such as feldspar porcelain, alumina porcelain and steatite porcelain. Electric porcelain is a type of porcelain insulators used in power industry systems, which are made from natural minerals such as bauxite, kaolin, and feldspar as main raw materials, and are used in electric power industry systems, including various line insulators and electrical insulators for power stations, and other live bodies Insulating parts for isolation or support.

[Classification of electric porcelain]

It is usually classified according to the product shape, voltage level and application environment of electric porcelain. According to the shape of the product, it can be divided into: disc suspension insulator, pin insulator, rod insulator, hollow insulator, etc.; according to the voltage level, it can be divided into: low voltage (AC 1000 V and below, DC 1500 V and below) insulator and high Voltage (over 1000 V AC, over 1500 V DC) insulators, among which there are ultra-high voltage (330kV and 500 kV AC, 500 kV DC) and UHV (750kV AC and 1000kV, 800kV DC) among high-voltage insulators; according to the characteristics of use It can be divided into: line insulators, power station or electrical insulators; according to the use environment can be divided into indoor insulators and outdoor insulators; and so on.

【Application of Electric Porcelain】

Electroceramics are mainly used in various voltage levels of transmission lines, substations, electrical equipment, and other special industries such as rail transit power systems to connect conductors or components of different potentials and play an insulating and supporting role. Such as the disc suspension insulators and long rod insulators used for tension or suspension of high-voltage lines, rod-shaped post insulators used for substation bus or equipment support, hollow insulators used for transformer bushings, switchgear, capacitors or transformers Wait.
