AC voltage test systems with transformer design are used to test high voltage products (like high voltage cables, power transformers, GIS), components (bushings, arresters), and insulating materials. They can be used in a variety of applications, such as routine, type testing, in particular, wet testing, also indoor / outdoor testing, on-site testing.
The test transformers are of cylinder insulating shell design with steel cover and base, the insulating cylinder is made of reinforced fiberglass, covered with a moisture-rejecting insulating paint. And dielectric materials consist of paper, transformer board and transformer oil.
The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space. Rated voltage of single module can be up to 750kV, we have successfully experienced 2400kV test transformer by four modules cascaded.
Model：YDTW / YDTCW
Current：Up to 5A
