Improved DC Properties of Polypropylene HVDC Cable Insulation by Grafting and Blending Combined Modification

open access: yesHigh Voltage, Volume 11, Issue 1, Page 73-82, February 2026.
ABSTRACT In order to meet the needs of mechanical properties of cable insulation, polypropylene (PP) needs to be blended with low modulus materials to achieve toughening and softening. However, the compatibility between two or more resins can significantly affect the electrical properties of the composites.

The effect of degassing on morphology and space charge

open access: yes, 2004
It is believed that space charge buildup in cross-linked polyethylene (XLPE) insulation is the main cause for premature failure of underground power cables. The space charge activities in XLPE depend on many factors such as additives, material treatment,

Dielectric model of water trees in an XLPE cable

open access: yes, 2008
In this paper a water-tree degraded insulation is modeled as a matrix composed of cubic cells. In the model there are three types of cells: pure XLPE, XLPE with water inclusion and the XLPE cell with a cylindrical water channel.

FTIR characterization of aged XLPE

open access: yesPolymer 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
