·Introduction:

YDTW series devices refer to partial discharge-free frequency test transformer produced by our firm by bring the techniques form home and abroad. They are widely used in producing equipments, cables, electric machine, transformer, mutual inductor, insulating materials and related high-voltage unit, etc. They also apply to electric power, sciencific research and colleges’high-voltage experiment. They help to do the experiments of partial dischage and frequency voltage withstand test. PD-free test transformer adopts epoxy barrel structure, which contribute to its low discharge and losses, little weight, small waveform distortion. They are high-quality equipments and accord with the standard of DL417-91、JB/T9641-1999、GB1094.1～1094.5-85、GB6451.1～6451.5-86.
