The high voltage winding is multi-layer cylinder type, the impact distribution is good, and the high strength acetal enamelled round copper wire is used. The coil is wound directly on a rotating die consisting of a gear plate and a soft paper tube which is stuck on the iron core post. The yoke insulation and trapezoidal pad are integrated into one, so that the body is evenly compressed. A new type of hanging plate positioning structure, longitudinal and transverse positioning, to ensure that the body is stable and not displaced.

Oil tank: mainly corrugated oil tank. It can also be designed as a rectangular chip radiator tank.
