| Abstract | In this paper, the operation life, electrical and mechanical characters of operation aging silicone rubber composite insulators as well as aging phenomena of these composite insulators caused by natural multi-factors were researched and analyzed based on surface physical characters examination of the silicone rubber composite insulators including electronic-microscope and scan electronic-microscope inspection, etc., and electrical insulation tests including power frequency voltage test, impulse voltage test, etc,. According to these results of research and analysis, the residual safe operation life of these composite insulators may be evaluated in this paper. Comparing with 20 years theoretical operating life of silicone rubber composite insulators, these test specimens of insulators shew us that their operation life did not exceed 10 years, that is, the early aging phenomena of these specimens was caused by multi-factors such as mineral filler, pollution, ultraviolet radiation. All the silicone rubber composite insulators which were produced in the corresponding period should be replaced as soon as possible. |

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.
