| Polymer composites offer numerous advantages over traditional ceramic materials and occupied place as emerging outdoor insulators. However, due to their organic nature they are affected by multiple stresses which in turn damage the integrity of these materials and reduce their life. To deal with these challenges not only design of these insulators has been improved but different types of fillers were also studied and tested for improvement of their properties. In this review article, stresses responsible for the degradation of properties of composite insulators and different types of fillers used for the improvement of these properties are presented. Furthermore; literature in this field has been used to identify the research gaps. An overview of effort initiated by authors to fill the gaps up to possible extent is also presented at the end. |
