IMPROVEMENT OF DIELECTRIC STRENGTHS FOR CROSS-LINKED POLYETHYLENE (XLPE) MEDIUM VOLTAGE CABLES
International Journal of Research -GRANTHAALAYAH, 2019 The electricity distribution companies are interested of the types of polymeric materials used in medium voltage cables which is considered the basis of power grid. In this study, it tried to enhance the electrical properties of cross-linked polyethylene (XLPE) after adding inorganic filler: such as Silica (SiO2) filler with 10%, 20%, 30% and 40 ...

Correlation Between Thermal Parameters and Morphology of Cross-Linked Polyethylene
IEEE Access, 2020 This paper reveals a correlation between morphology and thermal parameters on cross-linked polyethylene (XLPE) cable with different insulating states. Several cables were selected to detect the physicochemical and thermal parameters of the XLPE.

Algorithm for load cycling correction to minimise the dry zone influences on the cross‐linked polyethylene (XLPE) cable insulation [PDF]
IET Generation, Transmission & Distribution, 2020 Dry zone formation around underground power cables during load cycling may lead to thermal failure of the cable's insulation. This phenomenon has to be recorded to send an alarm to the maintenance crew when the soil around the cable reaches the critical value at which the dry zone has started to be formed.
