The AK flexible insulation is a product deriving from the coupling of aramid paper (usually 50µ thick) with polyamide film (25µ). This material represents a high performance solution for the insulation of electric motors and more generally of rotating machines with working temperatures up to 180°C.
It is used in the insulation of the slot and in the closure of the same (little tile), as well as to separate the phases on the heads of the windings. It can also be used in transformers and static electrical equipment as an interlayer insulator.
