“…However, with the requirements for higher voltages (e.g. 275kV), superconducting cables had considerable dielectric losses [7]. In such voltages, in order to reduce dielectric losses, other insulating materials were used (e.g.…”

In this paper, a short review is given on insulating materials at very low temperatures. Various insulating materials are investigated in terms of phenomena such as partial discharges. Some of the factors affecting the behavior of the insulating materials at very low temperatures, such as the quality of electrode surface, the stressed insulation volume and the existing bubbles, are also reported and commented upon. Proposals for future research are also discussed.

“…In case of cold dielectric cables conventional insulation cannot be used and a special insulation system able to operate reliably at cryogenic temperature must be used instead. In the last decade hybrid insulation systems based on pressurized liquid nitrogen in the range 63-77 K and polypropylene laminate paper (PPLP) able to operate up to 275 kV in ac condition [23][24][25][26][27] and 80 kV in dc [13], have been successfully developed thus opening the way to practical penetration of HTS cable technology. The feasibility of hybrid insulation based on pressurized liquid hydrogen at 20 K and crepe paper, able to operate up to 50 kV in dc condition, has also been demonstrated recently [11].…”

The advantages of using HTS cables for dc transmission and distribution are quantitatively investigated. 2G-HTS cables with LN 2 cooling are considered. MgB 2 cables with LH 2 cooling or with two stages LH 2 / LN 2 cooling are considered as well. A design procedure is first set up to arriveat the sizing of the cryopipes in order as to have a realistic estimation of the cooling power required. Losses and right of way of HTS cables are calculated and compared with those of conventional solutions by following a system approach, which takes into account the possible different power architectures of the two cases. Cost comparison is also carried out. Bulk energy transmission by means of HTS HVDC link is dealt with. Feasibility of medium voltage HTS dc connection of a large offshore wind park is assessed. Finally, low voltage HTS dc distribution for data centers, aluminum smelters and ships is investigated.

“…Nowadays there are at least 5 factories that promise to produce high homogeneity 2G wires with hundreds of meters [1][2][3]. Considering the coated conductors applications for electrical power system, the fault current limiters and the cables for energy transmission are technology with higher level of maturity, and they are also becoming commercial products [4][5][6][7][8][9]. Notwithstanding, the investigation of those devices is the goal of several international research groups in order to improve the design and performance of these equipments.…”

Since the second generation (2G) superconducting wires started to be produced in a large scale almost a decade ago, the quality of the materials manufactured has been continually improved. Every year the manufacturers present new materials with better electrical properties, increasing the critical current density, critical magnetic field and the total length produced with continuous homogeneity. The mechanical properties of the coated conductor should be taken in account, since electro-dynamical forces appear in working conditions as stress in the cooling and heating processes. In applications as fault current limiters, SMES, transformers, electromagnets, motors, cables, etc., the consideration of them is mandatory to the project of those devices. In this context, the present work studies the electrical and mechanical properties of 12 mm 2G wires samples under torsion without axial tension. Critical current is measured as a function on the torsion angle. Details of the experiment and their results are here presented.
