(Summary description)1) The coil is damp.
2) The thickness and number of layers of the insulating layer do not meet the requirements.
3) The coil margin distance and creepage distance do not meet the requirements.
4) The skeleton is cracked, allowing moisture to penetrate.
5) The coil is not dried when dipped, the insulating paint is not filmed, and the insulating resin is not cured.
6) The moisture in the coil is not removed before the coil is dipped. When the coil is dried after dipping, the insulating paint on the surface of the coil has been dried and cured, but the interior has not been cured to form a film.
