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

ABSTRACT The ± 200 kV direct current (DC) cables of the Zhoushan Transmission Project were targeted, and crosslinked polyethylene (XLPE) insulation samples were prepared from faulty and spare cables. Samples were tested for oxidation induction period, Fourier transform infrared spectroscopy, differential scanning calorimetry, thermally stimulated ...

Towards Recyclable Insulation Materials for High Voltage Cables
The preferred material for modern extruded high voltage transmission cables is cross-linked polyethylene (XLPE). This material has excellent thermo-mechanical and dielectric properties, however it is not easily recycled at end of use, raising questions ...
