A transmission cable includes a conductor or a bundle of conductors extending along a longitudinal axis, which is circumferentially covered by an insulation layer having an extruded insulation material, whereby the transmission cable passes the electrical type test as specified in Cigr&#xe9; TB496, whereby the rated voltage Uis 450 kV or more. The type test includes subjecting the power cable to a DC voltage of 1.85*Uduring 10 to 15 cycles at negative polarity, followed by a polarity reversal with another 10 to 15 cycles at positive polarity at a DC voltage of 1.85*U, followed by additional 2 to 5 cycles during at least 4 to 10 days at positive polarity, and wherein Uis 450 kV, or 525 kV, or more.
