Introduction Recent studies have shown that sequential irradiation/annealing processes improves the wear performance and oxidation resistance of crosslinked polyethylene, while maintaining mechanical properties [1,2]. Although these early results showed great promise for mechanically enhanced XLPE, we still know little about the variables that can lead to high-wear, particularly surface roughne...
Incorporating positive temperature coefficient (PTC) ceramic particles into polymers provides a prospective alternative solution for suppressing severe electric field distortions caused by negative (NTC) of electrical resistivity within polymer insulation in high voltage direct current cable. The effect the Curie PTC on inhibition NTC cross-linked polyethylene (XLPE) is investigated this study....
Cross-linked polyethylene (XLPE) is primarily used as a coating and insulator for electrical wires cables. The cross-links render recycling through remelting unfeasible, XLPE waste usually incinerated or sent to landfills. Previous investigations showed that increased the impact strength of commodity thermoplastics. Hence, incorporating in polyamide 12, an engineering thermoplastic, was studied...
In this paper, N, N’-m-phenylene dimaleimide (HVA-2) grafted crosslinked polyethylene (XLPE) insulation materials with different HVA-2 contents were prepared. The grafting, crosslinking, and crystalline structure characterized by Fourier-transform infrared spectroscopy (FTIR), Soxhlet extraction, differential scanning calorimetry (DSC), respectively. space charge distribution, direct current (D...
The composite insulation composed of cross-linked polyethylene (XLPE) and silicone rubber (SiR) is common in high voltage direct current cable accessory installation. However, the space charge accumulation, especially interfacial accumulation XLPE/SiR, poses a serious threat to safe operation accessories, its transport mechanism still unclear, at micro-scale. In order investigate simultaneous m...
The role of a series of functionalized graphene additives in power cable insulation in suppressing the growth of electrical treeing and preventing the degradation of the polymer matrix has been investigated by density functional theory calculations. Bader charge analysis indicates that pristine, doped or defect graphene could effectively capture hot electrons to block their attack on cross-link...
A multi-sensor joint detection technology was proposed based on the theory of the high frequency current transformer (HFCT) method, Ultra-high frequency (UHF) method and acoustic emission (AE) method. An experimental partial discharge (PD) testing was applied on XLPE cable with artificial defect signals. The experimental results show that the multi-sensor joint detection technology will help to...
Abstract The goal of this study is to see how different chemically modified nanoparticles affect the performance and characteristics commercial cross-linked polyethylene (XLPE) as a polymeric insulator used in insulating power cables compare their properties order figure out what factors are most important improving XLPE properties. Silicon dioxide or silica, titanium dioxide, zinc oxide nanopa...
Crosslinked polyethylene (XLPE) has become the globally preferred insulation for power cables, both for distribution and transmission system applications. This insulation system provides cost efficiency in operation and procurement, as well as lower environmental and maintenance requirements when compared to older impregnated paper systems. The purpose of this paper is to outline some of the de...
he undergrounding of energy transmission cables is widely recognized as a good means to provide reliable supplies of power at a low total cost [1], [2]. As utilities increasingly acknowledge this and install many more high voltage (HV) and extra high voltage (EHV) cables, they will face a major challenge: namely, sourcing the increased amount of high quality power cable with the cable manufactu...
