FTIR characterization of aged XLPE

Polymer Testing, 2006
The effects on macromolecular structure brought about by accelerated ageing in linear and crosslinked polyethylenes were detected and quantitatively monitored by using the ATR-FTIR technique. The thermo-processing conditions used in the preparation of samples with various crosslinking levels lead to the formation of by products such as acetophenone and

Investigation of the Impact of XLPE Cable Ageing on Impedance Mismatch Characteristics and Unbalanced Behaviour in Hybrid Operation Systems

High Voltage, Volume 11, Issue 2, Page 544-555, April 2026.
ABSTRACT In the Hainan–Guangdong interconnection project, oil leakage in oil‐filled cables required replacing the faulty core with a single core from a three‐core cross‐linked polyethylene (XLPE) cable, leading to mixed operation of XLPE and oil‐filled cables.

Recent update on crosslinked polyethylene in total hip arthroplasty

SICOT-J, 2020
More than two decades after their clinical introduction, crosslinked polyethylenes (XLPE) have been widely adopted. Though concerns were initially raised regarding oxidation and brittleness, on a large scale, the first generation of XLPE continues to be ...

Electric Field Determination in DC Polymeric Power Cable in the Presence of Space Charge [PDF]

, 2007
The pulsed electroacoustic (PEA) technique was used to perform space charge measurements in polymeric power cables. However, for a practical dc power cable the electric field is affected by conductivity of the material, which is a function of both ...

Dielectric Loss Suppression of Polyethylene Cable Insulation by Motion Restriction of Ultralow‐Content Grafted Maleic Anhydride

High Voltage, Volume 11, Issue 2, Page 534-543, April 2026.
ABSTRACT Maleic anhydride (MAH) grafting modification is an effective approach to enhance the insulating performance of polyethylene (PE) cable insulations. However, the high polarity of MAH often causes considerable dielectric loss, making it unsuitable for AC systems.

The influence of physical and chemical linkage on the properties of nanocomposites [PDF]

, 2005
It has been shown by several groups that the mechanical and electrical behavior of composites changes quite substantially, and often beneficially, when the filler particle size is less than 100 nm in diameter.

Combustion Performance of Silicone Rubber Polymer Insulation Material Under Damp‐Heat Ageing Conditions: Molecular Insights Into the Effects of Structural Changes on Macroscopic Properties

High Voltage, Volume 11, Issue 2, Page 589-599, April 2026.
ABSTRACT Silicone rubber (SR), an organic silicon polymer material, is known for its excellent heat resistance and mechanical properties. It is widely used in composite insulators and cable accessory materials. However, the ageing caused by humidity and heat significantly impacts its performance, an issue that cannot be ignored. This paper investigates

"Sub-Hertz" Dielectric Spectroscopy [PDF]

, 2005
Dielectric spectroscopy measurements below 1 Hz are often dominated by “conduction-like” effects. For this reason, they often appear to be dismissed as being of little interest.
