Eight spiral laminar voltage regulation coil's of 220kV a little over fixed knot constructs

The utility model relates to the technical field of transformers, relate to an eight spiral laminar voltage regulation coil's of 220kV a little over fixed knot constructs. Including voltage regulation coil, voltage regulation coil's both sides odd position presss from both sides the centre gripping through a wire respectively, and two PET ligature area ligatures of wire double -layered quilt parallel arrangement are fixed, and the wire presss from both sides middle bottom and is equipped with the low groove that compresses tightly a little over position, and the wire presss from both sides the upper portion both sides and is equipped with the upper groove that supplies PET ligature area to pass respectively. The utility model discloses an eight spiral laminar voltage regulation coil's of 220kV a little over fixed knot constructs carries out the centre gripping to the coil odd through the wire clamp, and reuse PET ligature area ligature wire presss from both sides, so greatly increased voltage regulation coil
