1. Voltage Stabilisers for XLPE Cable Insulation
Sammanfattning : The demand for energy in the Western world has istorically increased steadily and a steady increase is forecasted for the next decades. This steady increase together with the huge merging markets in India and China are setting new standards for the energy transmission. LÄS MER
2. Characterization of Conduction and Polarization Properties of HVDC Cable XLPE Insulation Materials
Sammanfattning : Since its first introduction in 1998, extruded direct current (DC) cable technology has been growing rapidly leading to many cable system installations with operation voltages up to 320 kV. Cable manufacturers invest heavily on technology development in this field and today extruded DC cable systems for operation voltages as high as 525 kV are commercially available. LÄS MER
3. Characterization of Conduction and Polarization Properties of HVDC Cable XLPE Insulation Materials
Sammanfattning : High voltage direct current (HVDC) cables with extruded insulation system were introduced in 1998. Since then this technology has been growing rapidly with many installations that are today operational at voltages up to 320 kV. LÄS MER
4. Residual Stresses and Strains in Cross-linked Polyethylene Power Cable Insulation
Sammanfattning : The subject of this thesis is modeling of the manufacturing process of high voltage power cables with the aim of predicting residual stresses and strains in the cable insulation. The studied material is cross-linked polyethylene (XLPE), which at room temperature is a semi-crystalline viscoelastic solid. LÄS MER
5. Techniques for Localization of Insulation Degradation along Medium-Voltage Power Cables
Sammanfattning : Time Domain Reflectometry (TDR) has been used for localization of transmission line discontinuities in diverse applications. Various challenges have to be addressed when applying TDR for localization of insulation degradation in power cables. LÄS MER
