Electromechanical effects in XLPE cable models
Proceedings of 1995 IEEE 5th International Conference on Conduction and Breakdown in Solid Dielectrics, 2002The authors present an XLPE cable model. They show that experiments confirm the essential features of the Lippmann equation now developed to include bulk effects. Moreover the value of the compliance deduced from the equations is of the right order of magnitude and of the correct temperature dependence.

Reduced neutral XLPE cable design
IEEE Transactions on Power Delivery, 1990The authors describe the theoretical, laboratory, and economic analyses undertaken by B.C. Hydro to determine the optimum metallic concentric neutral design for its single-conductor 750 and 500 kcmil aluminum XLPE (cross-linked polyethylene) 15 kV and 25 kV insulated concentric-neutral-type feeder cables.

Thermoelectric aging of cable grade XLPE
Conference Record of the 1998 IEEE International Symposium on Electrical Insulation (Cat. No.98CH36239), 2002Many data have been reported relating to the electrical endurance of polymers. These data show that the performance is reduced by electrical and thermal stressing in wet conditions. In many present applications however, the cables function in their dry state since they include an effective moisture barrier.

Development of XLPE-Moulded Joint for High Voltage XLPE Insulated Cable
IEEE Power Engineering Review, 1983This paper describes the design of the cross-linked polyethylene moulded straight joint for 154 kV and 275 kV cross-linked polyethylene insulated cables, the moulding method, the characteristics of the moulded insulation, and its frist application to a long distance 154 kV XLPE cable transmission line in Japan (Toyo-Ike Line of The Tokyo Electric Power

Partial Discharge Measurement for Cable Terminators of XLPE Power Cable
2007 IEEE International Conference on Solid Dielectrics, 2007This paper presents a partial discharge (PD) measurement for cable terminators of XLPE power cable. The power cable of rated voltage 24 kV and a cross sectional area of 240 mm2 was used in the experiment. The partial discharge level and dielectric loss are very important factors to indicate the insulation quality of power cable.

Long Term Behavior of XLPE Insulated Cable Models
IEEE Power Engineering Review, 1987A test cycle with electrical, thermal and combined stresses has been performed on models of XLPE insulated: cables in order to characterize this type of cable from the viewpoint of endurance to combined stresses. For this purpose the method of Combined Analysis of experimental data has been used, thus permitting the goal to be reached in less than two ...

Water content of XLPE cable components
Proceedings of 1994 IEEE International Symposium on Electrical Insulation, 2002This paper presents results of water absorption measurements in several insulation and shield materials taken from unaged medium-voltage cables made by three different manufacturers. Comparisons are made of the water content of two types of water tree retardant XLPE (WTRXLPE) insulation with a conventional XLPE material, and two cleaner conductor and ...

An Investigation into the Growth of Electrical Trees in XLPE Cable Insulation
IEEE Transactions on Electrical Insulation, 1979This paper describes the effects of frequency, voltage, temperature and mechanical stress on the times to breakdown of XLPE cable insulation subjected to highly divergent fields. Temperature and mechanical stress reduce the times to breakdown but tests with increasing voltage and high frequency produced unexpected results which could not be explained ...
