through our good quality and credit in the industry. Such as the projects of Zhongnanhai, Yellow
River drinking water, the Bird's Nest etc, some of them have applied our products.
In 2002, the company passed the ISO9001:2000 quality management system. On this foundation,
we are strictly in accordance to the quality management system s provision, and supply high
quality products and after-sales service for the users in every manufacture links.
We possess several domestic experts, whom are engaged in the investigation of mutual inductor.
And we have the most advanced full-automatic winding machines, soldering machines, full-
automatic mutual inductor verifying devices, soft magnetic materials characteristics monitors, and
other kinds of electrons, electric instruments, which may provide different kinds of usage of mutual
inductors. Such as: current, voltage and electric energy measurement, electromotor transformer s
protection and mutual inductor for generatrices and differential protection, and other special usage
of medium frequency current transformer, zero sequence current mutual inductor, open type current
transformer, signal sampling mutual inductor, and different types of mutual inductors.About Us
