Which material is the most resistant to high temperatures?

As for which material the rod strut porcelain insulator is resistant to high temperatures, it usually depends on the specific formulation and production process of the insulator, rather than a single material. However, in general, porcelain insulators with special formulations and processes tend to have high temperature resistance.

Taking the ultra-ultra-high-strength outdoor rod pillar porcelain insulator as an example, its body is made of bauxite, feldspar, mullite, Zhangcun soil, Anko panning soil and Chen furnace soil as raw materials, and is made by ball milling and grinding, sieving iron absorption, spray granulation, isostatic pressing and billet pressing, cutting processing, sandblasting glazing and high-temperature firing. This kind of insulator has the characteristics of fine grains, high density, high specific gravity and high dispersion, so the compressive strength and bending withstand load are high, and can meet the performance requirements of insulators in the 550~1000kV UHV transmission grid, including high temperature resistance.

In addition, with the development of science and technology, some new materials are also used in the manufacture of rod pillar porcelain insulators, and these new materials may have higher high temperature resistance. However, it should be noted that the high temperature resistance of an insulator depends not only on the material, but also on a variety of factors such as its structural design, manufacturing process, and use environment.

Therefore, it is not possible to give a clear answer as to which material the rod strut porcelain insulator is resistant to high temperatures. When choosing an insulator, it should be selected according to the specific use environment and requirements, and comprehensively considering the material, performance, price and other factors. At the same time, attention should also be paid to regular inspection and maintenance of the insulator to ensure that its use is normal and to prevent failure in a high-temperature environment.
