【DESCRIPTION】：The service life of capacitor is limited. The life span of capacitor with different brands and technologies is different. The replacement time of capacitor is closely related to its quality, operation environment and type selection.

Capsun metallized film photovoltaic DC filter capacitor has excellent manufacturing process, uniform spraying area and long service life. On the contrary, the poor quality metallized film will lead to the rapid aging of capacitor dielectric, which will lead to failure. What's more, if the installation environment of the capacitor is bad, the environment temperature is high, there is a lot of dust or there is no good ventilation measures, the service life of the capacitor will be reduced. Secondly, the selection of capacitor is also a big condition. In the installation and matching, whether the reactor with the same harmonic content is correctly selected, and whether the reactor quality and capacitor rated voltage selection are in line with the enterprise equipment operation are related to the service life of the capacitor.

Capsun capacitor put forward the concept of dry-type power capacitor earlier, and was first applied to large-scale industrial production. The material of capacitor uses metallized polypropylene film, which has strong advantages compared with traditional capacitors on the market: Microwave pattern trimming technology, dry structure, gas protection, built-in discharge resistance, overvoltage protection and self-healing ability.
