30 mm heavy ice area ground wire pre-twisted wire type strain string of plus/minus 800 kV super-high voltage DC line

The utility model provides a 30 mm heavy ice area ground wire pre-twisted wire type strain string of a plus/minus 800 kV super-high voltage DC line. It is characterized in that a GD-type cake hanging point is adopted. The GD-type cake hanging point is next to a U-shaped ring I closely. The U-shaped ring I matches with a U-shaped ring II mutually and the rings are connected together. Then the U-shaped ring I and the U-shaped ring II connects with a pre-twisted wire type strain clip through a DB-type adjusting plate and a matched U-shaped ring III, thereby realizing the connection of the whole string. The 30 mm heavy ice area ground wire pre-twisted wire type strain string of the plus/minus 800 kV super-high voltage DC line in the utility model has beneficial effects. The 30 mm heavy ice area ground wire pre-twisted wire type strain string of the plus/minus 800 kV super-high voltage DC line in the utility model has better performance than a common power transmission line ground wire tension string in an technic
