Development of 500‐kV XLPE cables
Electrical Engineering in Japan, 1996 A 500-kV XLPE insulated cable with an insulation thickness of 27 mm has been developed for long-distance transmission lines. Basic studies on the 500-kV XLPE cable have shown that contaminants in the insulation may determine electrical performance. This hypothesis is justified by the good correlation obtained between statistical estimations of the size

High Voltage, EarlyView.ABSTRACT A time domain pulse (TDP) based on the frequency domain reflectometry (FDR) method can be used to diagnose the insulation state of cable defects. However, because of the limitations of the FDR test instrument, the lack of a reflection coefficient spectrum (RCS) in the low‐frequency band (LFB) can result in low frequency oscillation in the time

Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Wind energy has become one of the most promising new energy resources. In the construction of offshore wind farms, the cable accounts for about 10% of the total investment, and the optimization of the cable layout is necessary for reducing the total cost of the wind farm. In this paper, we proposed a novel algorithm for the optimization of the

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation
Advanced Functional Materials, Volume 36, Issue 30, 13 April 2026.A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...
