In 2018, the company realized sales income of 107 million yuan, realized a profit of 410,000 yuan, and produced a total of 3.31 million products. The income of high-tech products in total revenue was 66.04 million yuan, accounting for 62% of total revenue.

In the early 1980s, the company exclusively introduced the complete design and manufacturing technology and key equipment of German AEG NT and NGT fuses. The company's products have been upgraded and reached the international advanced level. The company has become a leading manufacturer of fuses. In the early 1990s, it invested heavily in technological transformation, introducing German WISTRA, DORST, H&G's special production equipment for melt pipe production and J.M's fuse assembly semi-automatic production line. In the late 1990s, the company adjusted its product structure and involved in the development of high-voltage fuses and miniature circuit breakers. It is the first company to introduce high-voltage fuses for oil-immersed full-range protection and high-voltage fuses for wind power that fill the international gap. It has become the leading technology for American high-voltage fuses. The miniature circuit breaker has developed a miniature circuit breaker with selective protection through the method of production, education and research, which solves the problem that the terminal circuit breaker cannot achieve effective selective protection for the first time. High-voltage fuses and miniature circuit breakers have formed production capacity and sales scale, laying a foundation for the sustainable development of enterprises.

After years of market development, a complete sales network has been established. A number of well-known enterprises in major industries in the country have established business relationships with the company. Product quality and service satisfaction have won the trust of customers and the company has a good reputation.
