TL;DR: In this paper, the feasibility of HVDC cables and the development of different types of cables and accessories are reviewed and the non-uniform electric field distribution caused by the applied voltage, temperature dependent conductivity, and space charge accumulation is briefly discussed.

TL;DR: A comprehensive experimental investigation of XLPE and its nanocomposite with fumed silica (SiO2) has been performed by CIGRE Working Group D1.24, in cooperative tests conducted by a number of members; covering materials characterization, real and imaginary permittivity, dc conductivity, space charge formation, dielectric breakdown strength, and partial discharge resistance as discussed by the authors.

TL;DR: In this article, the authors investigated the lamellar morphology of melt-crystallized isotactic polystyrene and found that hexagonal lamellae splay apart about a common diagonal presenting three characteristic projections in orthogonal directions.

TL;DR: In this article, the authors compared traditional isotactic and syndiotactic polypropylenes to a range of commercially available propylene co-polymers and focused on their morphology, thermal, thermo-mechanical and electrical properties.

TL;DR: In this article, a mixture of linear and branched polyethylene was prepared covering the composition range 1-20% linear polyethylenes, and three thermal treatments were subsequently chosen to produce a range of different morphologies.
