| Abstract: | The composite post insulator is firstly applied to 750 kV disconnector under the severe environment of heavy wind and sand,strong solar radiation,large temperature difference between day and night etc.Therefore,higher requirements are raised for the composite insulator for its mechanical ＆ electrical property,and outer insulating ageing performance.The composite post insulator for 750 kV disconnector is developed through the research of key technology,such as insulation structure dimension,core filling,layer structure,ageing of the housing and forming process etc.This type of insulator has been approved by the authoritative organization and applied to 750 kV transmission ＆ distribution projects. |
