Abstract: A transmission system includes an electrical conductor and an insulation layer circumferentially covering the conductor. The layer includes at least two layer sections including a plurality of sublayers concentrically orientated, whereby each sublayer comprises one or more strips arranged beside each other in a circumferential direction. Gaps are formed between adjacent edges of strips and each gap is covered by a strip of an adjacent sublayer. Each of the strips includes one or more sheets arranged beside each other in a radial direction. Each sheet includes an insulation material including cellulose paper and polymer. At least one sublayer includes at least one sheet of said cellulose paper, and at least one sublayer including at least one sheet of said polymer, and whereby the insulation layer is impregnated.
