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. Voltage Stabilizers: From Design to Synthesis, Processing and Electrical Characterization
Sammanfattning : 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.

3. 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
4. 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
5. Thermoplastic Insulation for High Voltage Cables
Sammanfattning : High voltage direct current (HVDC) cables that seamlessly integrate renewables have an important contribution to the modern world’s efforts towards a more sustainable future. Extruded HVDC cables that efficiently and reliably transport electricity require robust insulation materials with good thermomechanical and dielectric properties. LÄS MER
