    Recently, the number of installed high voltage DC (HVDC) links using cables with extruded insulation has dramatically increased, since extruded insulation has several advantages over traditional oil-paper insulation for cables: easier splicing, no oil use, and higher service temperature [1], [2]. Conversely, a disadvantage of HVDC extruded cables is space charge (SC) buildup with HVDC. This is a c... View full abstract»

    The market for high voltage DC (HVDC) transmission systems has increased dramatically the last few decades. This is mainly due to the economic, electrical, and environmental advantages for bulk power transmission over long distances. Also, in some cases, such as for long subsea cable links, HVDC is the only option. HVDC cables have traditionally used oil-paper for insulation, with the most common ... View full abstract»

    This contribution provides an assessment of the present major electrical insulation candidates, under development or ready for commercialization, for high-voltage DC (HVDC) extruded polymer cables in Europe, Japan and China. It is a contribution on behalf of the Dielectrics and Electrical Insulation Society (DEIS) Working Group on HVDC Cable Systems. It is noted that interest in extruded polymer H... View full abstract»

    Cross-linked polyethylene (XLPE) has replaced oil-paper insulated systems as the primary solution for medium and high voltage AC cables decades ago, since they enable marginally higher operating temperatures and can be produced with high throughput and well-controlled extrusion technology [1]. The base for this insulation is polyethylene (PE), which can be crosslinked either with peroxide cure (in... View full abstract»

    More than ever, controlling the amount of space charge that accumulates in high voltage DC (HVDC) extruded cables under electrical stress and a thermal gradient is a major challenge to ensure a good level of reliability of the cable and therefore a good availability of energy [1]. It is now clear that, although studies on space charge are absolutely necessary to understand the charge accumulation ... View full abstract»

  • Life and reliability models for high voltage DC extruded cables

    Aging of electrical insulation is the irreversible degradation of its dielectric properties due to applied stresses. Aging eventually leads to insulation failure, which in practice means breakdown. In this framework, a “life model” is a mathematical relationship between time to failure, also referred to as “life” of the insulation, and the levels of applied stresses. In... View full abstract»

    With the development of high voltage DC (HVDC) transmission, considerably more attention has been paid to aging of the insulation. The inverse power law (IPL), which reflects the service endurance capability of insulation and is used to determine the test voltage for the prequalification and type tests [1], [2], is given as L = t E n, (1) where L and n are material constants, t is the time to fail...
