2. New Test Arrangement for Measuring Electrical Treeing in Polymers
Abstract : Electrical treeing in high voltage cable insulation has been studied for a number of years and today the mostly used laboratory test set-up is the needle-plane electrode configuration. In this thesis a different type of electrode configuration is described. READ MORE

3. The Effect of Crosslinking on Morphology and Electrical Properties in LDPE Intended for Power Cables
Abstract : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is often made by peroxide initiated crosslinking of low density polyethylene (LDPE). The introduction of unsaturations, i.e. READ MORE

4. Voltage Stabilizers: From Design to Synthesis, Processing and Electrical Characterization
Abstract : Voltage stabilizers are additives capable of inhibiting electrical treeing; a degradation mechanism for insulation materials subjected to strong divergent electric fields. The intended use is in cross-linked polyethylene (XLPE) high voltage power cable insulation where minute defects in the manufacturing process can give rise to the conditions needed for the initiation of treeing, which in the worst case scenario leads to failure of the insulation system with blackouts and expensive repairs as a consequence.

5. Characterization of Different Interface Types for HVDC Extruded Cable Applications
Abstract : In extruded HVDC cable systems a variety of interface types can be found, and the interfacial properties depend on the application within the system. Such applications can be joints, terminations or the cable itself and they will all have different material combinations and manufacturing methods. READ MORE
