Note, however, that the C−H bond angles are not 90° as this diagram would indicate, but are approximately 110°, since each carbon atom is tetrahedral. (Wikipedia.org)

Morphological changes in polyethylene under electrical stress

T. Noon; D. K. Das-Gupta IEEE 1997 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 1997

The results of infrared spectroscopy showed that orientational changes occur in electrically stressed (>4×107 V m -1) low density polyethylene (LDPE). Furthermore, an investigation of highly crystalline polyethylene with X-ray diffraction spectrometry show that the sizes of para-crystalline region varied by approximately 12 Å and the crystalline regions were seen to change in size by approximately 3 Å for the ...


Transient current pulses in gamma-irradiated polyethylene

H. M. Banford; R. A. Fouracre; G. Chen; D. J. Tedford 1988. Annual Report., Conference on Electrical Insulation and Dielectric Phenomena, 1988

Transient pulses or spikes of current under direct applied fields were observed in LDPE (low-density polyethylene) following gamma irradiation in ambient air to doses between 104 and 106 Gy. This pulse activity is a function of field strength, dose, and temperature. It is concluded that the origins of the pulses are probably either gas production or charge generation


Performance evaluation of charge storage in corona charged polyethylene film

Lu Tingji Proceedings of 8th International Symposium on Electrets (ISE 8), 1994

For some fluoropolymer films, such as Teflon FEP etc., their charge stability can be remarkably improved by the application of heat during corona charging, but polyethylene (PE) is an exception. In this paper, the behavior of corona charged PE film at elevated temperatures was studied. Using the phenomenological model derived by R.L. Remke et al. (1983), the attempt-to- escape frequencies ...


Electrical conduction in low-density polyethylene

G. Chen; H. M. Banford; R. A. Fouracre; D. J. Tedford Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics, 1989

Charge transport in additive-free low-density polyethylene (LDPE) was investigated by examining the behavior of both steady-state and transient currents as well as thermally stimulated discharge currents (TSDCs). The transient current behavior indicated space-charge-limited current (SCLC). The carrier mobility calculated from the transient SCLC curves was in agreement with other measurements and was found to increase with the square of the ...


Effect of ethylene content on bowtie trees and wet electrical performance in filled EPR insulation materials

Amalendu Sarkar; Mark Easter; Ed Walcott; William Temple; John T. Smith 2010 IEEE International Symposium on Electrical Insulation, 2010

The insulation for extruded medium voltage power cables currently used world- wide are based on two broad categories of polymeric materials: crosslinkable elastomers, consisting of Ethylene Propylene Rubber (EPR)*, and crosslinkable low density polyethylene, consisting of Crosslinked Polyethylene (XLPE) or Tree Retardant Crosslinked Polyethylene (TRXLPE). These two broad categories have over 40 years of proven field performance. A considerable amount ...

  • Main Principles of HVDC Extruded Cable Design

    This chapter illustrates, in detail, the basics of HVDC extruded cable design. It presents a detailed analysis of the differences between HVAC and HVDC cables. The chapter also presents a detailed analysis of the DC electric field distribution in the typical transient conditions encountered during the service of an HVDC cable. It discusses the influence of the laying environment temperature on the steady field of an HVDC extruded cable and the effects of impulses superimposed to the DC voltage, which gives rise to a novel statistical approach to the selection of impulse voltage test levels for HVDC extruded cables. The chapter presents an overview of the problems involved by the modification of the stress distribution by trapped space charge effects. It reviews the polyethylene-based dielectrics for designing and manufacturing HVDC extruded cables, and morphology of polyethylene from the viewpoint of its influence on the performances of HVDC cable insulation.
