Treeing phenomenon of thermoplastic polyethylene blends for recyclable cable insulation materials

AIP Advances, 2017
Owing to its good recyclability and low processing energy consumption, non-crosslinked polyethylene blends (e.g. LLDPE-HDPE blends) are considered as one of potential environmental-friendly substitutions for crosslinked polyethylene (XLPE) as cable ...

DC electric field distribution in planar dielectric in the presence of space charge [PDF]

, 2007
Electric field in a dielectric material under dc conditions is determined by conductivity of the material. It is well known that the dc conductivity is a function of both temperature and electric field.

The effect of degassing on morphology and space charge

, 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,

Space charge accumulation under the effects of temperature gradient on solid dielectric DC cable

, 2009
It is well known that existence and accumulation of space charge within the insulating material poses threat to the reliability in the operation of dc power cables. When the cables are loaded under high voltage direct current (HVDC), temperature gradient
