Polyethylene Nanocomposites for Power Cable Insulations

Investigation of electrical treeing in cable grade crosslinked polyethylene (XLPE) insulations

Using PC-based on-line monitoring system, extensive measurements were performed in insulation blocks cut from the crosslinked polyethylene (XLPE) insulation of 36, 69 and 132 kV rated cables produced in Saudi Arabia. A needle-plane electrode system was used with a needle radius of 10 m. The role of 'applied voltage step-time duration' and associated time resolved initiation and growth of diffe...

Synthesis and Characterization of Chrysotile/Polyethylene Nanocomposites

Polyethylene/chrysotile nanocomposites with different amount (0.4 to 6.7 wt%) of filler were prepared by in situ polymerization method using the metallocene Cp2ZrCl2 as catalyst and methylaluminoxane (MAO) as co-catalyst. Previous to polymerization, raw chrysotile was treated by three different methods that used thermal treatment and acid leaching. In method A, raw chrysotile was treated therma...

Structure and Dynamics of Polyethylene Nanocomposites

The structure and dynamics of linear monodisperse polyethylene (PE) melts (C160H322 and C440H882) containing homogeneously distributed spherical nanoparticles were investigated. The PE chains were simulated using a coarse-grained model and a Monte Carlo algorithm. Two variables were considered: (i) the wall-to-wall distance between particles d and (ii) the interaction energy between monomers an...

Development of Polymer Packaging for Power Cable

S. Sremac, P. Gladović, M. Đelošević, B. Matić, A. Matić, Faculty of Technical Sciences, University of Novi Sad, Novi Sad, Serbia. This paper discusses the issues of product design and the procedure of developing polymer packaging as one of the most important engineering tasks. For the purpose of packing power cables a polymer packaging has been designed in the form of drum. Packaging and many ...
