In the domestic market, there are many small current grounding line selection manufacturers. Many manufacturers choose to sell small current grounding line selection for profit. Many suppliers have no production line, or only produce and sell a simple small current grounding line selection device. Because of the low production cost, they reduce the price, disturb the market price and vicious competition, resulting in uneven product quality. However, there are not many manufacturers that can really do a good job of small current grounding line selection device. These powerful manufacturers often lose customers because of the high quotation of small current grounding line selection device.

This phenomenon occurs frequently. The essence of selling at a low price is to "drive out good money with little money". In short, it means that poor quality products drive good quality products out of the market. Because in the face as like as two peas, consumers will prefer to choose cheaper products. The raw materials of cheaper products will be worse than the raw materials of the expensive products. Slowly, the products with good quality but no expensive ones will be bought. The harm is that all the line selection manufacturers in the market blindly reduce the price, which leads to no profit for the small current grounding line selection device manufacturers, so they do not do the research and development of such products. It's not only in this industry, but also in any industry.

However, the power system is related to people's livelihood. The economic loss caused by the wrong or untimely line selection of a grounding fault is far greater than the purchase price of 10 sets of high price small current grounding line selection devices.

Therefore, in the selection of products, the selection of manufacturers is the key. Manufacturers can show the type inspection report, patent certificate and more qualifications of the company.
