Abstract: The present disclosure relates to a method of building an insulation system around a naked conductor section of a power cable, which power cable has a conductor which includes the naked conductor section and which power cable comprises an insulation system already provided around a majority of the conductor. The insulation system comprises 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, and which conductor has a naked conductor section. The method comprises: a) placing the naked conductor section in a mould, and b) moulding an insulation system around the naked conductor section, wherein the moulding of the insulation system involves injecting a first semiconducting compound into a first mould cavity to form an inner semiconducting layer around the naked conductor section, injecting an insulation compound into a second mould cavity to form an insulation layer around the inner semiconducting layer, and injecting a second semiconducting compound into a third mould cavity to form an outer semiconducting layer around the insulation layer.

Abstract translation: 本公开涉及一种在电力电缆的裸露导体部分周围构建绝缘系统的方法，该电力电缆具有包括裸露导体部分的导体，并且该电力电缆包括已经围绕导体的大部分设置的绝缘系统 。 绝缘系统包括布置在导体周围的内部半导体层，围绕内部半导体层布置的绝缘层和围绕绝缘层设置的外部半导体层，并且该导体具有裸露的导体部分。 该方法包括：a）将裸露导体部分放置在模具中，以及b）在裸露导体部分周围模制绝缘系统，其中绝缘系统的模制包括将第一半导体化合物注入到第一模腔中以形成内部 在裸导体部分周围的半导体层，将绝缘化合物注入到第二模腔中以在内部半导体层周围形成绝缘层，以及将第二半导体化合物注入第三模腔中，以形成围绕绝缘层的外部半导体层。
