According to the production raw material and the preparation method of the disc-shaped insulator with good insulating property, a main body raw material of the disc-shaped insulator comprises the following raw materials in parts by mass: 15 to 25 parts of aluminum oxide, 10 to 15 parts of high-potassium feldspar, 40 to 60 parts of clay, 0.1 to 1 part of lanthanum oxide, 0.1 to 1 part of cerium sesquioxide, 0.1 to 0.88 part of praseodymium oxide, 15 to 18 parts of nacrite and 15 to 18 parts of garnet. A disc-shaped insulator main body glaze raw material comprises the following raw materials in parts by mass: 15-20 parts of quartz, 2-5 parts of talc, 18-27 parts of kaolin, 1-3 parts of copper oxide, 1-3 parts of ferric oxide and 0.1-1 part of rare earth oxide. The processed insulator can have good mechanical strength, meanwhile, the processed insulator has good insulativity in use, long-term use of the insulator can be guaranteed, and the insulator is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a raw material for producing disc insulators with good insulation performance and a preparation method. Background technique [0002] Disc-shaped suspension porcelain insulators are the most used insulators for high-voltage overhead transmission lines. When in use, single-piece insulators are used to form insulator strings of a certain length according to the requirements of line insulation coordination. Support wire function. The insulator is mainly composed of porcelain parts, iron caps, steel feet and other parts cemented with cement adhesive, and can be divided into two parts: the head and the shed. During operation, it bears the comprehensive effect of tension, vibration, system voltage, various pollution and impact overvoltage, and can keep working in such an environment without damage all the year round. Therefore, the insulator is required to have high m...
