Claim:
1. An insulation system comprising: a metallic bar; a main insulation around the bar; a single first layer of a single tape of composite material comprising at least one first electrically conductive material and at least one hydrophobic material wrapped around the main insulation, a second layer of a different second electrically conductive material directly on the main insulation, and a third outermost layer of an electrically conductive material; and a fourth layer, between the first layer with the at least one first electrically conductive material and the at least one hydrophobic material and the main insulation, of an electrically conductive material, which is different from the at least one first electrically conductive material, wherein the electrically conductive materials of the second and third layers are different from the at least one first electrically conductive material, wherein the first layer is between the second layer and the third layer, wherein the single first tape comprises a woven fabric comprising fibers, each fiber comprising graphite and PTFE, wherein the single tape is one of one or more tapes wrapped around the main insulation, and wherein the tapes are in a form of a succession of windings, each winding having edges, and the edges of successive windings of the tapes abut each other.
