Failure Mechanisms in XLPE Cables
2021During the operation of the cables, their insulation is subjected to simultaneous or consecutive electrical, thermal, mechanical and environmental stresses. These stresses contribute to the initiation and development of some processes of XLPE degradation; processes that lead, in time, to the insulation breakdown and, therefore, to the removal and ...

Electrical conduction of a XLPE nanocomposite
Journal of the Korean Physical Society, 2014The resistivity, breakdown strength, and formation of space charges are very important factors for insulation design of HVDC cable. It is known that a nano-sized metal-oxide inorganic filler reduces the formation of space charges in the polymer nanocomposite.

Flame-Retardant Aspects of XLPE
2021Crosslinking of polyethylene is used to improve mechanical properties, thermo-mechanical performance and chemical resistance of polyethylene. Many applications of crosslinked polyethylene (XLPE) require some level of flame resistance, especially those applications that require the XLPE to be used in and around enclosed spaces, such as automobiles ...

Historical and Theoretical Background of XLPE
2021This chapter deals with the historical and theoretical analysis of crosslinked polyethylene (XLPE). The chapter is divided into three sections, the first section dealing with the historical developments in XLPE. This part depicted a historical picture of invention, the necessity of invention and finally its establishment as various XLPE products.

Crosslinked polyethylene finds widespread use as a thermoset material in various industries due to their superior thermomechanical properties. There are three common ways of crosslinking polyethylene via irradiation, peroxide and silanes. Irradiation and peroxide-based crosslinking technologies involve the use of radicals.

Electroluminescence for XLPE cable diagnosis
Proceedings of the 7th International Conference on Properties and Applications of Dielectric Materials (Cat. No.03CH37417), 2004Electrical treeing is responsible for the breakdown of power cables with polymeric insulation, such as low density polyethylene (LDPE) and cross-linked polyethylene (XLPE). Electroluminescence (EL) occurs in the initiation phase of electrical tree. We studied the characteristics of EL in XLPE cut from 77 kV class power cables.

Deterioration in aged XLPE cables
[Proceedings] 1992 Annual Report: Conference on Electrical Insulation and Dielectric Phenomena, 2003Electrical and material characteristics of 93 aged XLPE (cross-linked polyethylene) cables removed from the field after 2 approximately 19 years of service were measured. It was confirmed that breakdown strengths under AC, DC, and impulse voltages in such cables decrease with length of service.

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1975, 1975
Electrical defects in cross-linked polyethylene insulated cables (XLPE cable) such as voids and contaminants in XLPE or characteristics of XLPE such as crystallinity and microporosity have been investigated in relation to the electrical characteristics of XLPE cable. Very small defects which can be observed with a microscope are being investigated. The

IEEE International Symposium on Electrical Insulation, 2002
Impurity analysis by neutron activation was performed on several unaged and field-aged distribution cables differing in origin and manufacturing process (steam and dry curing). The results show principally that impurities found in the insulation can be attributed primarily to unclean semiconductive shields and to the manufacturing process.
