Currently, XLPE is widely used in underground high voltage cable. Recently, a few nanofillers have been selected by numerous researchers to enhance the electrical tree resistance in polymer matrix. In this paper, the influence of ZnO and Al2O3 nanofillers on the electrical treeing in XLPE have been investigated. The concentration of nanofillers loading are varies from 0.5 wt%, 1 wt% and 1.5 wt%. The...
The combination of polymer materials, such as silicone rubber (SiR) and ethylene propylene diene monomer (EPDM), has become one of the potential developments of new polymer insulator with superior characteristics. SiR/EPDM with a ratio of 50:50 weight percentages had produced the optimal electrical and mechanical properties of polymer composites. However, the study of these balanced blends with inclusion...
Electrical tree is the one of phenomena that can initiate to the electrical breakdown in polymeric insulating material. In this paper, the structure of electrical tree growth in Silicone Rubber (SiR) with different concentration of nano-alumina has been observed. The test specimen samples were prepared by mixing SiR base polymer with 0, 0.5, 1, 1.5, 2, 2.5 and 3 vol% of nano-alumina. The structure...
The introduction of nano technology gives many benefits to the consumers and industries especially in cable insulators fabrication. This technology offers better cable life time and better cable resistance to face the cable failure. With the inclusion of nano filler in unfilled polymer, it shows that the nano filler has the ability in refining the electrical, mechanical and thermal properties compared...
It is believed, by the addition of nano-filler into the SiR/EPDM blends could further improve its electrical properties. In this paper, the dielectric strength of SiR/EPDM composite with Alumina nano-filler for outdoor AC high voltage insulator has been investigated. Thus, the specimen with different loading concentration of Alumina nano-filler (1 Vol%, 2 Vol%, 3 Vol%, 4 Vol% and 5 Vol%) has been...
Wave power and offshore wind power has been recognized by the international community as a renewable clean energy source. Potential analysis on introduction of hybrid wave and offshore wind machine at particular site however requires the knowledge of the wind wave and swell wave power distributions. The work presented in this paper considers the possibility of using higher order statistical moments...
