What relevant matters should be paid attention to when choosing lightning protection products

There are many brands of lightning protection products on the market, with different quality and very different prices. What kind of lightning protection products are the products that meet the needs?

brand history

To decide whether to choose a brand of lightning protection products, we should first understand the origin of the brand and what position it is in the market to determine whether the manufacturer is a brand in the target purchase range. At present, the lightning protection manufacturers in the domestic market can be divided into two parts: international manufacturers and domestic manufacturers. The international manufacturers mentioned here refer to manufacturers whose business scope is not limited to the domestic market, otherwise they are regarded as domestic enterprises. According to factors such as the time to enter the Chinese market, the international manufacturer camp can be divided into three types. The first category is the earliest manufacturers to enter the domestic market, such as the German OBO. These brands have long entered the domestic market and bear the halo of German brands. They occupy a large share in the market. Of course, their prices are also top-notch. . The second category is the international manufacturers that have entered the domestic market in recent years. They are also some large-scale enterprises, such as DELTA (Delta) from Taiwan and ABB from Switzerland. ABB has a long-term technical accumulation in the field of low-voltage power distribution. It mainly sells lightning protection products in the domestic market. DELTA has always produced and sold a full range of lightning protection products in the international market. These are trusted by users in the international market. Brand. There are also some international brands from Eastern Europe and the United States, some of which are also surprisingly expensive. At present, Qianshilin is more active in the market. The common characteristics of international brands are the large scale of enterprises, high product prices, and relatively reliable quality. The price of DELTA is the lowest among international brands, which is very close to the prices of some domestic high-end brands.

Some of the domestic lightning protection manufacturers have also been operating in the domestic market for many years and become well-known brands, such as Sichuan Zhongguang. Of course, the prices of these brands are also significantly lower than international brands; Guangzhou Leixun is a newcomer among domestic manufacturers; With the gradual growth of the lightning protection product market, some manufacturers from Wenzhou have also launched their own lightning protection products. These brands have a large number of brands, low prices, and mainly target the low-end market. However, some of these companies have insufficient production processes, The problem that the product quality can not be fully met, it needs continuous efforts to catch up with the production level of large manufacturers.

Start with details and choose lightning protection products

I often hear people in the industry say that the quality of lightning protection products of international manufacturers is reliable, and domestic products are slightly inferior. In fact, we do not need to be biased against domestic manufacturers, but we do need to master some preliminary knowledge about the design and manufacture of lightning protection products. It is still helpful to judge the product quality. Let's talk about the factors that affect the reliability of lightning protection products from the aspects of material selection, testing procedures, design experience and so on.

Material determines quality

First talk about the materials. The main material of lightning protection products is zinc oxide varistor. The quality of the material and the level of the process have a direct impact on whether the product can produce the expected protection when it is struck by lightning. Some manufacturers use imported varistors. Objectively speaking, the quality is reliable, and similar products from China are another matter. Because the quality of this component is not good, the system will suffer direct losses when it is struck by lightning, so users When purchasing, you should first understand the source of the varistor. Generally speaking, the varistor of large manufacturers with international background is generally imported, and even a full set of lightning protection devices are imported, the quality is indeed guaranteed, but the price will be higher.

Design experience is not a triumph

Design experience is also an important factor that affects whether the lightning protector is functioning normally. In fact, the structure and circuit design experience of lightning protection products come from a summary of a large number of application cases. Just like the doctor's level depends on the experience of practicing medicine, it is not enough to study in school. Some large manufacturers with international background have accumulated decades of experience in the design of lightning protection products. This is indeed not something that small manufacturers that have just started to operate lightning protection products can have. Therefore, some small enterprises can clone the product designs of well-known enterprises, but they often fail to achieve the desired results.
