Dynamic of a Space Charge in Gamma-Irradiated Cross-Linked Polyethylene (XLPE)

2020 IEEE 3rd International Conference on Dielectrics (ICD), 2020
The aim of the present work is to study the dynamics of the space charge in cross-linked polyethylene (XLPE) irradiated by gamma rays. For this purpose, film samples peeled from cables have been irradiated with gamma rays at total dose up to 100 kGy, in air at room temperature.

Effect of Functionalized Graphene Oxide with Hyper-Branched Flame Retardant on Flammability and Thermal Stability of Cross-Linked Polyethylene [PDF]

, 2014
In this work, GO was functionalized by a hyper-branched flame retardant, which was synthesized by the reaction of N-aminoethyl piperazine and di(acryloyloxyethyl)methylphosphonate. Subsequently, the resultant functionalized GO (FGO) was incorporated into

Review of Edge-based Image Segmentation on Electrical Tree Classification in Cross-linked Polyethylene (XLPE) Insulation

Journal of Physics: Conference Series, 2021
Abstract Electrical trees are the degradation events most linked with partial discharge (PD) activity in cross-linked polyethylene (XLPE) insulation of high voltage (HV) cables. To investigate tree structures and forms, study of electrical tree structures for morphological analysis often carried out using optical microscopy.
