Composite hollow insulator are composed of FRP tube with silicon rubber housing and metal flanges,which is suitable for indoor and outdoor HV equipment.Developed since thirty years while gained experience in service near fifteen years,composite hollow insulators are more advanced than porcelain insulator,especiclly in specific requirement and operation environment,it behaves prethy well in respect of serviee safety and handling.the insulators conform to GB/T21429-2008.
Features
* Safety, In case of internal over-pressure or external man-made damages It leads to less harn to nearby equipment compared with porcelain insulator
* Light weight,easy transportation and handling with low damages
* High safety in earthquake-prone--No need for shock damper
* Excellent anti-pollution performance
* Unique anti-ageing performance proven by successful 15 years long experience in service
* Much shorted lead time compared with porcelain insulator
* Safety material health
