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.
 
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. In recent years, the photovoltaic business has continued to develop, and its revenue has been close to 40%, but its low-voltage electrical industry still occupies a dominant position, with a gross profit margin of more than 30% that is nearly half higher than that of the photovoltaic industry.
 
Compared with international brands such as Schneider and Legrand, CHINT's business is still concentrated in China, but compared with domestic electrical brands such as Feidiao and Bull, CHINT is one of the more successful overseas market layouts, accounting for 25% of the total revenue in overseas markets in 2017, and its products have also been recognized by other countries, participating in large and medium-sized projects such as the Finnish Metro and Petrobras' natural gas pipelines.
 
CHINT socket is divided into 2 series with higher price and 7 series at relatively cheap, compared with foreign brands, CHINT and other domestic brand sockets often have seven-hole products, the product adopts double two holes plus one or three holes design, compared with the normal five-hole socket seven holes can meet more needs, but the spacing between the jacks also becomes smaller, multi-device simultaneous use may interfere, more users with more two-hole plug appliances at home can consider buying.
 
CHINT 2H series ensures smooth plugging and unplugging for more than 10,000 times, embedded with anti-rust carbon steel skeleton, good compression and impact resistance, and strong reliability. The fly in the ointment is that CHINT 2H adopts the wiring method of screw crimping, which may cause damage to the wire if used for a long time compared to 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 43 yuan, and the unit price of the 2V series is 20 yuan.
 
CHINT's entry-level socket 7 series is equipped with safety protection doors and tin phosphor bronze current-carrying parts, which can ensure the safety of use. The overall thickness of the E7A series is only six millimeters, which is very thin in the same class of products, and the price is 7.9 yuan. The internal structure of the 7I series is still tight at the price of 6.9 yuan, the current-carrying parts will not shake, and the durability is strong.
