FORFARANDE FOR TILLVERKNING OCH IMPREGNERING AV DROSSLAR ELLER TRANSFORMATORER

摘要

A choke or transformer is provided with hooks which are integral with its casing (1) and which are engageable by a suspension rod (4) for conveying the chokes or transformers through an impregnation vessel. The hooks are formed by cutting and then bending part of the sheet metal forming the casing. This avoids having to clean the conveying means after impregnation has been carried out.
