1. A method of manufacturing a power cable comprising a conductor, semiconductor layers and insulation layers, the process comprising the steps of:
(A) Extruding about the conductor a first insulation layer positioned between first and second semiconductor layers to make an inner power cable comprising:
(1) The conductor which is in contact with,(2) A first semiconductor layer which is also in contact with,(3) A first insulation layer which is also in contact with,(4) A second semiconductor layer, and (B) Extruding about the inner power cable a second insulation layer positioned between third and fourth semiconductor layers to make the power cable with a total insulation thickness of greater than or equal to 9 mm, the power cable comprising the inner power cable of which the second semiconductor layer is in contact with:
(5) The third semiconductor layer which is also in contact with,(6) The second insulation layer which is also in contact with,(7) The fourth semiconductor layer.
