Abstract:
1. An insulation system over a bare bar of a stator bar comprising an anti-corona tape being wound in a half-lapped manner over the entire periphery and over the entire length of the bare bar; wherein the anti-corona tape comprises multiple first sublayers and multiple second sublayers, wherein each of the first sublayers being electrically insulative and each of the second sublayer has an electrically resistance of greater than 200 ohm/sq and less than 1000 ohm/sq, with the second sublayer engaged to the periphery of the bare bar, and the first sublayer alternating with and engaging the second sublayer; and wherein each of the second sublayers comprises a patterned metallized coating comprising area of low electrical resistance parallel to a width of the first sublayer electrically connected with areas of high electrical resistance parallel to a length of the first sublayer.
