-Currently, THT is the official distributor of GE protective relay products in Vietnam market. The electrical system in Vietnam uses a lot of GE relays provided by THT. All of them work stably and receive high performance ratings from the users.
* The motor is a common and very diverse load to suit the requirements of the user. Therefore, the problems that can arise in the engine process are also diverse. As one of the leading engine manufacturers in the world, GE understands this problem and has found many advanced solutions to solve this problem. GE relays incorporate advanced new technologies to make monitoring, protection, and engine control easier and more efficient. From there, improve the efficiency and longevity of the engine.
