“…Hosier et al found that insulating materials obtained by blending iPP with ethylene-propylene copolymers exhibit good mechanical toughness and electrical properties [10]. As shown in Figure 3, the PP (as labeled with H) shows a lower temperature dependence-conductive current than that of PE (as labeled with 1,2,3,4,5) [11].…”

Due to its excellent electrical and thermal performance, as well as satisfying the needs for developing the environmentally friendly and recyclable cable insulation material, polypropylene has caused widespread concern. Nanodoping can effectively improve the electrical, thermal and mechanical properties of polypropylene nanocomposites, which provides a new method to solve the problems in its application in HVDC cable insulation. This chapter introduces research achievements on polypropylene and polypropylene/inorganic nanocomposites, which states the effects of nanodoping on the electrical properties, such as space charge behaviors, electrical tree aging, breakdown strength, etc. thermal conductivity and mechanical properties of the polypropylene and its multi-blends. The aging mechanism under different conditions is also discussed. The analysis shows that the surface treatment of nanoparticles can reduce the aggregation of nanoparticles and strengthen the interface effect, thus improving the comprehensive properties of polypropylene nanocomposites. This chapter also summarized the feasibility and future development of the polypropylene and its nanocomposites application in the insulation of HVDC cables.

“…This gave rise to improved electrical, thermal and mechanical properties of PP-based compounds (e.g. Syndiotactic PP [sPP]-based plus PE plus antioxidants) versus XLPE [45][46][47][48][49][50][51]. Some studies also highlighted issues of PP-based materials with flexibility, low temperature toughness, overall mechanical properties, which require deeper studies on dielectric properties of such materials [46,52].…”

“…As a last, but not least remark about HVDC extruded cable technology, let us also mention a breakthrough that emerged in this field since the mid 2010s with the advent of new polymeric "Poly-Propylene (PP)"-based extruded insulation for HVDC cables. The main reason is that, at the start of 21 st century, the search for environmentally friendly, fully recyclable, high performance insulation for HVDC cables pushed R&D towards PP-based thermoplastic compounds, as PP has excellent dielectric and heat resistance properties [26,[45][46][47][48][49][50][51][52]. As a consequence, in the last 2 decades, an extensive R&D activity was carried out on the basic structure of PP, intrinsic modifications, possible nanocomposites.…”

High Voltage Direct Current (HVDC) underground and submarine cables constitute an essential technology for the long‐distance transmission of renewable electrical power with low losses, thereby fostering decarbonisation. In the past 2 decades, all this yielded a quasi‐exponential rise of HVDC cable systems installed worldwide, but has also made the working conditions of HVDC cables harsher. In this paper, the contribution of HVDC cables to decarbonisation is tackled, with particular reference to the situation in Europe, and a few simple calculations showing in general terms the quantitative contribution provided by HVDC cable systems to decarbonisation are given. Then, the major issues towards long‐lasting and reliable HVDC cable systems are summarised briefly, focussing—for the sake of brevity—on the influence of the main HVDC cable technologies, of cable laying environment and of duty service. Some hints are also provided at the chances given by multiterminal HVDC systems.

“…Syndiotactic PP (sPP)-based compounds with the addition of PE and antioxidant blends were investigated [138], finding better electrical, thermal, and mechanical properties of sPP vs. isotactic PP (iPP), atactic PP (aPP), PE and XLPE [139]. Also, by blending iPP with ethylene-propylene copolymers, insulations were attained with good mechanical and electrical properties [140], and lower temperature dependence of electrical conductivity than PE [141]. Some studies also showed issues with flexibility, low temperature toughness, and overall mechanical properties of PP-based materials, as well as the need for deeper studies on their dielectric properties, e.g., conductivity and space charge behavior [134,142].…”

The improved features of AC/DC converters, the need to enhance cross-country interconnections, the will to make massive remote renewable energy sources available, and the fear of populations about overhead lines have fostered HVDC cable transmission all over the world, leading in the last two decades to an exponential increase of commissioned HVDC cable projects, particularly of the extruded insulation type. Comprehensive surveys of the issues to be faced by HVDC extruded cable systems appeared in the literature some years ago, but they are not so up-to-date, as HVDC extruded cable technology is developing fast. Therefore, the contribution this paper aims at giving is a systematic, comprehensive and updated summary of the main present and future issues and challenges that HVDC cable systems have to face to further improve their performance and competitiveness, so as to meet the growing quest for clean and available energy worldwide. The topics covered in this review–treated in alphabetical order for the reader’s convenience–are accessories, higher voltage and power, laying environment (submarine and underground cables), modeling, multiterminal HVDC, operation and diagnostics, recyclable insulation, space charge behavior, testing, thermal stability, transient voltages.
