Arrangement having a spiraled conductor strand, and method for producing such an arrangement

An arrangement, comprising:

• a spiraled conductor strand including a plurality of strand elements;
• and
• an annular winding support supporting said spiraled conductor strand, said winding support having a first abutment and a second abutment, and said winding support including a plurality of mutually abutting segments;
• said spiraled conductor strand ending on both sides of at least said first abutment but leaving said first abutment free of said conductor strand, and said spiraled conductor strand running beyond said second abutment;
• said spiraled conductor strand or one of said strand elements being wound onto one of said mutually abutting segments to initially wind a left-handed helix and, upon reaching an end of a segment, to insert a right-handed helix into free spaces located between helix loops of said left-handed helix, or vice versa, with respective crossing-over of said left-handed and right-handed helices.

A method for producing a measuring transformer, the method comprising:

• providing a winding support as an insulating ring having a first segment and a second segment;
• winding a spiraled conductor strand as a crossing-over helix onto the annular winding support by initially winding a first helix onto the first segment and winding a second helix onto the second segment;
• joining the first and second segments together to form a ring in a rim base of a ring electrode;
• and
• potting the first and second segments, the first and second helices and the ring electrode in an insulating material.
