Thermoluminescence in XLPE cable insulation
IEEE Transactions on Dielectrics and Electrical Insulation, 1996Crosslinked polyethylene (XLPE) has been employed in underground transmission and distribution cables because of its excellent electrical and mechanical properties, such as low permittivity and dielectric loss, high degree of toughness, and good flexibility.

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

A contribution to the study of aging of XLPE insulated cables
IEEE Transactions on Power Delivery, 1991The electrical, thermal, and multiple-stress (thermal and electrical) aging of cross-linked polyethylene (XLPE) cable models has been investigated in order to get information on aging effects and mechanisms. After endurance tests, XLPE cable models have been subjected to chemical, physical, electrical, and microstructural characterization.

Development of XLPE insulated DC cable
Electrical Engineering in Japan, 1994AbstractThis paper describes the development of dc XLPE cable. Through a series of material investigations, an XLPE compound containing highly purified special filler was developed.To check the dc insulation performance of the cable insulated with this new material, a prototype cable with 9 mm insulation thickness was manufactured.

Water content of XLPE cable insulation
Conference Record of the 1992 IEEE International Symposium on Electrical Insulation, 2003The authors deal with water absorption and diffusion in various kinds of cross-linked polyethylene (XLPE) cable insulation: steam-cured, dry-cured, and with and without water tree retardant (WTR). Measurements were performed on pieces of insulation directly or on cable specimens immersed in water at different temperatures.

Degradation of XLPE and PVC cable insulators
2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2015Thermal degradation mechanisms of automotive cable insulators made of PVC and XLPE matrices have been investigated by FT-IR spectroscopy. Impact of degradation at the macroscopic scale was monitored by uniaxial tensile testing and dielectric spectroscopy. It is found that elastic and fracture properties drop well before insulation properties.

Treening effects in PE and XLPE insulation
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1972, 1972Recent visual examination of unfilled polyethylene (PE) and cross-linked polyethylene (XLPE) insulation removed from cables which had been in service for a number of years, revealed so-called treeing patterns in some of the examined specimens.1,2 Electrical trees, originated by partial discharges, have been observed for a long time in various types of ...
