Conductor handling tool and a method of applying an electrically insulating material

A method of producing a transformer, comprising:

• producing a first electrical coil by winding a first wire to a first raw coil, providing at least one first conductor portion protruding from the first raw coil, wherein the at least one first conductor portion is a first electrical connector, inserting the first electrical connector into a conductor receiving section of a first conductor handling tool having a curved plate-shaped tool body such that a first tapered blade edge of a first tool body is directed away from the first conductor portion, winding a first tape of a first electrically insulating material onto at least a portion of the first raw coil, splitting a portion of the first tape by the first blade edge, and removing the first conductor handling tool from the first conductor portion after splitting;
• producing a second electrical coil by winding a second wire to a second raw coil, providing at least one second conductor portion protruding from the second raw coil, wherein the at least one second conductor portion is a second electrical connector, inserting the second electrical connector into a conductor receiving section of a second conductor handling tool having a curved plate-shaped tool body such that a second tapered blade edge of a second tool body is directed away from the second conductor portion, winding a second tape of a second electrically insulating material onto at least a portion of the second raw coil, splitting a portion of the second tape by the second blade edge, and removing the second conductor handling tool from the second conductor portion after splitting;
• providing a transformer housing;
• and
• placing the first electrical coil and the second electrical coil in the transformer housing so that the first electrical coil and the second electrical coil are inductively coupled.

A conductor handling tool comprising:

• a curved plate-shaped tool body, the tool body comprising:
• a conductor receiving opening for receiving a conductor portion and for holding the conductor portion received,
• wherein an edge of the plate-shaped tool body is shaped as a tapered blade edge extending within a y-z-plane, and directed away from the conductor receiving opening, and
• wherein the tapered blade edge forms an convex outer circumferential portion of the tool body for splitting a portion of insulating material during a winding of the insulating material.
