| Abstract | For UHV applications, the main challenge on insulator design is to fulfil the required length and mitigate the negative effects on insulation and mechanical performance caused by the increased length. Efforts can be made on system design by reducing the levels of switching over-voltages. The required creepage distances could also be reduced through the use of insulators with hydrophobic surface. Indoor solution can provide the conditions to reduce the required arcing distance by the improvement of the electrode design. In this report, the impacts of system parameters on the insulator design have been reviewed. On the other hand, Insulators with different type of materials and production techniques have been developed and are available. These include the porcelain insulators with hydrophobic coatings, hybrid insulator, and composite hollow-core insulators with different solution for internal insulation. It is important to know the strength and weakness of these insulators in order to make a correct selection. In this report the design issues and solutions related to external and internal insulation design of insulators for UHV applications have also been reviewed with emphasis on the post insulators made of composite hollow-cores. |
