110kv UHVDC reclamation unit

HVDC transformers are used as coupling elements between AC grids and high-power rectifiers for very long overhead lines or submarine cables. Converting AC lines to DC can help increase the power transfer volume through existing rights of way and typically cuts line losses by 30-50%.

  • Study on the Influencing Factors of Insulator on the Back

    The current research results indicate that the insulator’s insulation performance has a very important influence on the back-flashover lightning withstand performance of UHVDC transmission lines, especially for ±800 kV voltage level. However, it is not clear which factors will influence the insulation performance of the insulator, and the influencing mechanism is also not clear yet.
