    Development of Lead Test Sample Preparation

    High voltage cables play a key role in the production and distribution of renewable energy across the world, which is essential to tackle the climate change. Subsea high voltage cables are being installed between countries and continents and also connect windfarms and oil platforms to the mainland. A lead tube is usually introduced in subsea high voltage cables to prevent ingress of water into the cable insulation. As the lead tube is essential for the performance and lifetime of the cable system, the  quality of the lead tube has to be carefully controlled, which involves chemical and mechanical testing of the lead. However, the mechanical properties of the lead material as well as its toxicity put challenges to prepare the test samples in a precise, efficient and environmental manner. In addition, as testing of the lead tube material is a part of the cable manufacturing process, the time required to prepare the test samples needs to be optimized.
     
    The content of the work

    The objective of this thesis is to invent smart and efficient methods to produce flat test pieces from a lead tube. The proposed main activities can be summarized as follows:
     

    • Literature survey that covers chip-free cutting of lead and other soft metal alloys
    • Develop a method to cut test samples from led tubes of varying dimensions
    • Develop a method to make the extracted samples flat
    • Optimize the time required to prepare the prepare the test samples
    • Write the final report
