In recent years, with the development of electric power and information industry, people put forward higher requirements for power quality, shunt capacitors have been widely used. However, along with the development of technology, the market requirements for capacitor metallization film are getting higher and higher. As a power capacitor manufacturer, Cook Cooper will introduce the difference of metallized film for shunt capacitors in the next article.

What is the difference between metallized films of parallel capacitors

1、Common types of metallization film

Shunt capacitor metallization film, there are several types of zinc metallization film, aluminum metallization film, zinc aluminum metallization film and silver zinc aluminum metallization film. Currently capacitors commonly used metallization film, is zinc aluminum metallization film and silver zinc aluminum metallization film.
2, zinc aluminum metallization film characteristics

Due to the zinc, aluminum two atoms will diffuse each other, aluminum atoms to the metal surface will enhance the antioxidant capacity of the metal zinc layer. However, because the aluminum content is relatively low, the chemical nature of zinc is very active, so in the humid environment, zinc aluminum metallization film is prone to oxidation corrosion phenomenon.

3、Characteristics of silver zinc aluminum metallization film

Compared with zinc-aluminum metallization film, silver zinc aluminum metallization film has corrosion resistance, oxidation resistance, and silver zinc aluminum metallization film performance are better than zinc aluminum metallization film.
