What about Doketi capacitors? Are imported capacitors really much better than domestic ones?

Imported brand capacitors depend on whether they are imported in original packaging or whether the imported brand is produced domestically. In addition, there are some imported brands that are outsourced production, which are divided into foreign foreign cooperation and domestic and foreign cooperation. Foreign outsourcing is similar to original imports, that is, the use of other foreign brands and foreign production plants for production; The other is the domestic OEM of imported brands, that is, the domestic brand factories produce on behalf of them, which is no different from domestic ones.

The domestic excellent brands are: Surong, Xirong, Guirong, etc., these brands specialize in the production of capacitors.

The differences in raw materials and production processes have led to differences in product performance, and I personally believe that the main difference is in capacitance loss and product service life. In addition to Dukaiti, the original imported capacitor brands such as German electronicon, hydra, frako, etc. have excellent performance in loss and product life, the service life is generally more than 15 years, the failure rate is low, and the dielectric is generally self-healing polypropylene film, low loss; It adopts the way of filling and oiling, which is advanced in technology, green and environmentally friendly, and has light weight, which reduces the cost of import. The domestic capacitor inflation technology is not particularly mature, and most of them use oil-filled and epoxy resins.

The service life is not as good as that of imports, and the replacement frequency is relatively high; Of course, because the cost input is not the same, imported brands are generally higher than domestic products, with more and more developed logistics and more and more fierce market competition, imported brands are becoming more and more close to the people, after all, the cost performance of imported brands is still very high, and it still occupies a large part of the market seats.

The capacitor is made of a large margin of parameters, which may be safer.

The real ducati capacitors and reactors seen are the same as those on the English **, and the deviation on the capacitor label is indeed 5% 10%, and the Chinese sample seems to be just fooling the Chinese who do not understand foreign languages.

I also saw a lot of capacitor manufacturers' Chinese-English ** comparison, Tysen-kld, Celia, RTR, EPX, etc., all different, some have no English** also said to be imported, really to China everything can be different. All changed the parameters to be high, in order to cater to the psychology of Chinese chasing high.

Problems with friends upstairs.

1) Life expectancy: The life of the capacitor is greatly related to the aging of the capacitor film, and the difference between the rated voltage and the working voltage is inversely proportional to the aging speed of the film. Examples:

A 10kV capacitor used in a 400V system may be used for 1,000 years; It is recommended that this friend find a capacitor manufacturer to learn more.

2) Capacitance tolerance: 5% 10% is the IEC standard, and all manufacturers produce higher than this parameter. Even the most inferior capacitors are higher than this standard, but the degree is different.

3) Dielectric losses of capacitors: The dielectric loss is the minimum standard within the enterprise, but the actual measurement value of the authoritative organization is.

4) Altitude: English sample 2000m: China's altitude standard is weaker than the European altitude standard, and the European 2000 standard can be used at 4000 in China.

About the reactor in English ** is only the difference between color ** and black and white**. There is also the difference between a horizontal reactor and a vertical reactor.

There are more than 30 models of the reactor, and it is not possible to display all of them.

I'm a seller of Dukaiti products.

In fact, the domestic capacitors are also good, but the competition makes the products low-quality and consumable.

The main reason for Dukaiti products is that its technical indicators are relatively high, and the safety margin is relatively large.

Imported products, things are good, but they are high.

If you have the budget, you can buy it. However, there are many imported brands in the market now, such as Nokia, Kim Miller, Cap AG, etc., which are cheaper than Dukaiti.

Italian Governor Ketty is imported, the product is the best and the safety is high. However, it is expensive. There are other options for importing, such as electronicon and cap ag Capag capacitors are imported, and the choice still depends on the customer's positioning.

The quality of imported products is indeed better than that of domestic products, this is for sure. In the case of reactors, domestic and imported are actually almost the same. The main thing is the quality of the capacitor.

Pure imported brand, things can, but ** is too high. Capacitor + reactor group 360 to 500 yuan RMB per 1,000 yuan. The actual imported brands are not that expensive.

If you want to choose an imported brand, Ducati Italia has a choice, depending on your budget. Of course, there are other options, such as: Electronicon, Cap AG Energy Capacitors, etc., which can be referred to.

There are high pressure and low pressure products, which are different:

High voltage: 150 to 200 RMB per 1,000 yuan per capacitor monomer;

Low voltage: 460 to 500 yuan RMB per 1,000 yuan per group of electric cleaning container + reactor. Sleepy.

Note: Products with a large number of products are usually lower than products with a small number of products per 1,000 years, so products with a large number of products should be used as much as possible to consider the cost factor.

Ducati Italian Governor Catie chain manuscript brute group lead expensive, about 350 to 450 per thousand. In fact, it is not as expensive as shed or filial piety, you can choose other products electronicon, cap ag Kaipaji capacitors are imported, and the choice still depends on the customer's positioning.

Pure imported brand, things can, but ** is too high. Capacitor + reactor group 360 to 500 yuan RMB per 1,000 yuan. The actual imported brands are not that expensive.

If you want to choose an imported brand, Ducati Italy Ducati can choose, just look at Cong Han your pre-touch Chang. Of course, there are other options, such as: electronicon, cap ag energy capacitors, etc., ridiculous Zheng Zheng for reference.
