The present disclosure relates to an insulation material for a conductor bar of an electric machine. An object of the invention is to provide for an alternative insulation material in the field of electric machines. The object is solved by an insulation material for a conductor bar for an electric machine comprising glass-ceramic flakes made from a heat treated silica glass precursor in the shape of flakes. Further disclosed are a corresponding method and the use of glass-ceramic flakes as an insulation material for a conductor bar of an electric machine.

Insulation material and a method to produce

An arrangement includes conducting bar ends connected together and a cap) covering them filled with a putty. The cap is made of a resin containing a high thermal conductivity filler. The putty is a silicone elastomer containing a high thermal conductivity filler.

Arrangement of conducting bar ends

A method for insulating () a conductive bar () includes wrapping an insulating tape () around the conductive bar (), enclosing it in a flexible container (), applying a vacuum, impregnating the insulating tape () with an impregnating resin, curing the impregnating resin, and removing the conductive bar () with the insulation () around it from the flexible container (). In addition, together with the insulating tape (), an impregnating tape () made of the impregnating resin is wrapped around the conductive bar (). In order to impregnate, the impregnating tape () is melted.
