Understanding the Mechanism of Junction Effect of Homo‐Bilayer XLPE for HVDC Cable Factory Joints

High Voltage
In high‐voltage direct current cable systems, the factory joint of cross‐linked polyethylene (XLPE)‐insulated cables presents significant electrical breakdown risk. The charge accumulation mechanism at the XLPE–XLPE interface involves the accumulation of

Comparison of Production Processes and Performance Between Polypropylene-Insulated and Crosslinked-Polyethylene-Insulated Low-Voltage Cables

Energies
Traditional crosslinked-polyethylene (XLPE) insulation suffers from high recycling costs and low efficiency due to its thermosetting properties. In contrast, thermoplastic polypropylene (PP), with advantages of melt recyclability, low energy consumption,

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...

Current‐Generation Crosslinked Polyethylenes for Total Hip Arthroplasty: Mechanistic Insights Into Oxidative Stability and Antioxidant Efficiency

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 7, July 2026.
ABSTRACT Highly crosslinked polyethylene (XLPE) has revolutionized total hip arthroplasty (THA), but increased radiation doses and complex crosslink structures may increase oxidation susceptibility. The long‐term oxidative stability of XLPE depends on manufacturing factors, including crosslink density, antioxidant (vitamin E) concentration ...

Low‐Frequency Oscillation Suppression of FDR Time‐Domain Diagnostic Waveforms for Cable Defects Based on Splicing Technology

High Voltage, Volume 11, Issue 3, Page 681-691, June 2026.
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
