The enameled wire dielectric loss tester was developed by Shanghai Dean Electric Equipment Co., Ltd.? Dean electrician is the first brand in enameled wire industry?

Good question. Shanghai Dean Electrician has this excellent level. As early as 2004, the first domestic enameled wire dielectric loss tester was developed. Finally, there are many imitations, but they don't understand the main technology. I think it can only be the clearest enameled wire dielectric loss instrument in Shanghai Dean. It is said that Shanghai Dean Electrical Equipment Co., Ltd. has sold 200 sets of dielectric loss instruments all over the world. If I had to choose, I would definitely choose Dean brand!
