CHINT focuses on the research and development of low-voltage electrical products, with more than 100 series of products, covering many fields such as power distribution control terminals, and is one of the largest enterprises in the production and sales of low-voltage electrical appliances in China.
 
Among the local electrical brands, the qualifications of CHINT established in 1991 are not old, but the technology is developing very rapidly, its universal circuit breaker has won the first prize of scientific progress in China's machinery industry, and many of the company's products have passed the international CB safety certification, UL certification and many other international certifications, which can be called the leading brand in China at the technical level.
 
Speaking of CHINT, we have to mention another domestic electrical giant Delixi, the founder of the two companies has co-founded Yueqing County Refinement Switch Factory, and Nan Cunhui, who quit halfway, is now the head of CHINT.
 
Although Chint has a deep relationship with the domestic big brand Delixi, but now the development strategy of the two is not the same, Chint has a high degree of focus, and Delixi is very diversified. CHINT's business only involves the research and development of low-voltage electrical appliances and the photovoltaic industry, and in recent years, the photovoltaic business has continued to develop, and its revenue has approached 40%.
 
However, due to the fact that the development time of CHINT PV is not long, the initial construction expenditure is large, and the manufacturing of solar modules accounts for 25% of the total operating cost, so the profits of the low-voltage electrical industry are relatively higher, with a gross profit margin of more than 30%, which is nearly half higher than that of the photovoltaic industry.
 
For Chinese electrical brands, expanding overseas markets is a common problem they face, CHINT's way to answer the question is to practice hard internal skills, strengthen technical strength, and let foreign customers understand CHINT's products by participating in high-quality product exhibitions such as Hannover Messe, and participating in large and medium-sized projects such as Finland Metro and Brazil natural gas pipelines. In 2017, CHINT's overseas market revenue accounted for 25% of the total, an increase of nearly 4% over 2016.
 
CHINT switches are divided into two categories, the 2 series is more expensive, the 7 series is relatively cheap, CHINT 2H is embedded with anti-rust carbon steel fixing frame, good compression and impact resistance, and strong reliability. The fly in the ointment is that the 2H wiring method of CHINT is screw crimping, and the durability is not as good as that of saddle terminals. The slightly less expensive 2V series reinforces the fixed frame with two parts of steel on the left and right, replacing the one-piece steel skeleton, which reduces costs and ensures the strength of the shell. The price of the 2H series starts at 34 yuan, and the unit price of the 2V series is 19 yuan.
 
Although CHINT 7 series is entry-level, the contacts are still made of silver alloy, with high hardness and no arcing, which can ensure the safety of use. The load current of the E7A series can reach 16A, which is relatively rare in entry-level switches, and can be used for on/off control of air conditioners and water heaters, priced at 7.9 yuan. If it is only used to control lamps, the 7I series is also a good choice, and the tin phosphor bronze current carrier is still used at a price of 6.9 yuan, and the materials are very solid and durable.
