Abstract
A method of building an insulation system around a naked conductor section of a power cable. The insulation system includes an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer arranged around the insulation layer. The method includes: a) placing the naked conductor section in a mold, and b) molding an insulation system around the naked conductor section, wherein the molding of the insulation system involves injecting a first semiconducting compound into a first mold cavity to form an inner semiconducting layer around the naked conductor section, injecting an insulation compound into a second mold cavity to form an insulation layer around the inner semiconducting layer, and injecting a second semiconducting compound into a third mold cavity to form an outer semiconducting layer around the insulation layer.
