ULTRA HIGH POWER CABLE BY INSULATING THE CONDUCTOR

摘要

PURPOSE: An ultra high voltage cable with a strand insulated conductor is provided to reduce a transmission loss due to an AC resistor by coating a conductive layer of the ultra high voltage cable with enamel. CONSTITUTION: A plurality of protection layers protect a conductive layer(11). The protection layers include a semi-conductive layer and an insulation layer. An enamel coating layer is formed around a strand conductor(11-1). A strain insulated conductor(11-2) and the strain conductor are strained with a ratio of 6 to 9 : 1 to 4.
