Instroduction
Composits hollow insulators are composed of FRP tube with silicon rubber housing and metal flange,which is suitable for indoor and outdoor HV equipment.Developed since thirty years ago while gained in service near fifteen years,composite hollow insulators are more adveanced than porcelain insulators,especially in specific requirement and operation environment,it behaves prethy well in respect of service safety and handling.The insulatprs confirm to GB/T21429-2008
Features
It's more safer than [porcelain insulators.When internal over-pressure or external man-made damages occurs,it lead less harm to nearby equipmentHigh dafety in earthquake-prone area -No need for shock damperExcellent anti-pollution performanceUnique anti-ageing performance proven by successful 15 years long experience in serviceMuch shorted lead time compared with porcelain insulatorApplication
Composite hollow insulator is used for external insulation or support for following equipment:
Bushings
Arc-extinguides chambers and support insulators for circuit breakers
CT/PT,transformer bushings
Cable endings
Surge endings
1100kV composite hollow insulator assembled with switchgear
