ZTT ±1100kV DC composite insulator successfully passed Beijing appraising meeting in Beijing in 27 Dec, 2015.
All the members of the appraising meeting agrees ZTT±1100kV DC composite insulator should be put into production and operation in network as soon as possible with calculating operating experience.
Currently, the composite insulator has been applied in national new and key project lines and widely expected by power sectors. ZTT successfully developed ±1100kV DC composite insulator would be great help to national electric power construction.
