YDJ Series of light AC / DC high voltage test It is especially suitable for power system, industrial and mining enterprises, scientific research departments and other high-voltage electrical equipment, electrical components, insulation materials for the frequency or the frequency of the use of high- Under the high voltage of the insulation strength test is essential for high pressure test equipment.

YDJ The series of high-pressure test transformer adopts single-frame core structure.The primary winding is wound around the iron core and the high voltage winding is outside. This coaxial arrangement reduces the leakage flux, thus increasing the coupling between the windings. Into the core with a better octagonal structure, the overall appearance of nice. Its external structure shown in Figure 1, The internal structure shown in Figure2.
