Advantages of porcelain post insulators
Compared with glass insulators, the advantages of post porcelain insulators are mainly reflected in the fact that both have been used for more than several years.
Due to the manufacturing material of the post porcelain insulator, the mechanical strength brought by itself is very high, and the surface of the shell is not prone to cracks when subjected to external force. The electrical strength of ceramics can be very stable, and can even remain unchanged during use. Furthermore, the aging speed of ceramics is slower than that of glass, so in many cases glass insulators will become ceramic due to their own damage, while porcelain post insulator can continue to operate for a long time.
When the post porcelain insulator is damaged, the steel cap and ceramic fragments will be stuck, but the remaining undamaged part of the post porcelain insulator can retain the internal insulator string due to its high mechanical strength. And this is also a link that many circuit projects need to review when considering such products, that is, the self-breaking rate of large-scale grid insulation products.
The price of post porcelain insulators
The price of the post porcelain insulator is not very expensive in the market, the main reason is that it is small in size and the materials used are relatively cheap. As mentioned earlier, the post porcelain insulator is called this name because its material is mainly ceramics, and the main reason for choosing ceramics as raw materials is its insulating properties. The ceramic itself is not expensive, so the production cost of the overall post porcelain insulator is not very expensive.
However, in the initial stage of the development of the post porcelain insulator industry, due to the monopoly of the manufacturing technology of post porcelain insulators by large enterprises, the price of post porcelain insulators has been higher for a period of time. However, with the development of science and industry in China, various enterprises have developed the technology of post porcelain insulators and broke the monopoly, which made the price of post porcelain insulators stable to the current state.
