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.

Method for insulating a conductive bar

A high voltage stator bar includes a substantially quadrangular conductive element made of a plurality of interwoven strands, and an electric insulation applied around the conductive element. The permittivity at the corners of the electric insulation decreases by less than 60% from an inner insulation zone facing the conductive element towards an outer insulation zone.
