Electrical knowledge: the advantages of imported power capacitors

Click: Time:2022-12-27 13:44:12

Affected by the problem of reactive power in the power grid, enterprises have used power capacitors for reactive power compensation. There are two categories of imported capacitors and domestic capacitors on the market, and it is recommended that companies choose imported capacitors. So what are the advantages of imported power capacitors? The editor will introduce it in detail in the following article.

1. Better quality

The development of domestic power capacitors is late, and most of the manufacturer's technology comes from abroad. Therefore, the quality of domestic power capacitors is weaker than that of imported power capacitors. In addition to technical differences, some domestic capacitor manufacturers are fighting price wars, greatly compressing capacitor costs, and the quality of power capacitors produced is also worse.

2. Different substrates

In power capacitors, the choice of substrate is very important. In most cases, the quality of the substrate determines the quality of the metallized film. Compared with imported substrates, the quality of domestic substrates is relatively poor, and the quality of the produced products is also lower. The substrate used by imported capacitor manufacturers is of good quality, and the quality of the capacitors produced is better.

3. Cost-effective

Most domestic capacitors have low prices, mainly to compress product costs and reduce product quality. The price of imported capacitors is high, and there is no need to compress costs and reduce quality. Due to the poor quality of domestic capacitors, they will frequently fail and damage after operation, and enterprises need to replace them frequently. Compared with domestic capacitors, the advantage of imported power capacitors is that they have good quality and a lower probability of problems, which is the main reason why many companies buy imported capacitors.
