| Abstract | In order to improve the DC dielectric properties of cross-linked polyethylene (XLPE) insulation materials, carbon black (CB)/ XLPE nanocomposites were prepared with the melt blending method. The pulsed electro-acoustic (PEA) method was used to measure the space charge distribution of XLPE and CB/XLPE nanocomposites. The relationship between the DC electrical conduction and the applied electric field strength of each material was measured under several constant temperatures. The research results show that the amount of space charges significantly reduces when a small quantity of CB was added into XLPE. The ability of composites to inhibit space charges is strong when the CB content is 1 phr. It was found that the electrically conductive properties of XLPE present nonlinear characteristics under lower electrical field intensity. The electrical conductivity significantly increases with temperature. The electrical conductivity of the nanocomposites with CB is almost a constant value under the electrical field below 20 kV/mm, and the effect of temperature on the DC electrical conductivity obviously decreases, when temperature goes up. The addition o CB into the XLPE can effectively inhibit the internal space charge accumulation and improve the DC conduction characteristics of the composites. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
