What is electrical ceramics?
Application of electric porcelainPorcelain is mainly used in the transmission lines and various voltage levels in the power system substation, electrical equipment, power systems and other special industries such as rail transportation, the different potential conductors or components are connected and insulated and support role. As for disc type high-pressure line tension or overhanging insulator and long rod insulator, for substation bus or equipment support rod insulators, for transformer bushing, switchgear, capacitors or transformer hollow insulator etc..
Classification of electric porcelainIt is usually classified according to the product shape, voltage grade and application environment of electric porcelain. According to the shape of the product can be divided into: disc suspension insulator, pin insulator, rod insulator and hollow insulator; according to the voltage level can be divided into: low voltage (1000 V AC and DC below 1500 V and below) and high voltage insulator (above 1000 V AC to DC 1500V on insulator) the high voltage insulator and ultra high voltage (AC 330kV and 500 kV, 500 kV DC UHV (AC) and 750kV and 1000kV, 800kV DC) points; according to the use of features can be divided into: line insulators, power plants or electrical insulators; by the use of the environment can be divided into indoor and outdoor insulator insulators and so on.
Electrical ceramics, referred to as electric porcelain. In a broad sense, electric porcelain covers a wide range of electrical ceramics, including insulating ceramics, semiconducting ceramics, and so on. The planning of the porcelain only refers to porcelain insulator with bauxite, kaolin, feldspar and other minerals as the main raw materials by high temperature firing one applied in the electric power industry system, including a variety of line insulators and power insulators for electrical appliances, and other charged body isolation or support for insulation parts. Electric porcelain is an important basic component of power industry. The electric porcelain manufacturing industry belongs to the field of equipment manufacturing, which is supported by the national "11th Five-Year". It is the basic industry of the national economy
