The present disclosure provides a grounding structure, a method for assembling the same and a gas-insulated transmission line. The grounding structure includes a grounding guide defining a guiding hole and a grounding support fixed on the grounding guide and defining a cavity for accommodating a grounding contact. The grounding contact is arranged in the cavity and protrudes through the guiding hole on the grounding guide. The grounding contact is moveable along the wall of the cavity by a grounding spring accommodated in the cavity to realize the adaptive adjustment of the installation position. The grounding structure can be pre-assembled in an accurate and efficient way to avoid the components therein damaging, thereby improving the reliability and safety of the grounding structure and the gas-insulated equipment in which the grounding structure is used.

A helical jumper connector includes a helical support member configured to support a wire. The helical support member includes a first leg having a first helical winding and a second leg having a second helical winding that defines a second axial opening. The first axial opening and the second axial opening are coaxial with the wire when the first helical winding and the second helical winding are wrapped around the wire and cooperatively engage with one another to support the wire. A jumper casting is configured to receive the helical support member. The helical support member and the jumper casting are electrically conductive such that the helical jumper connector forms an electrically conductive pathway to carry electrical current from the wire. A method of making a helical jumper connector assembly includes applying a compression force to a helical jumper connector comprising a helical support member received in a jumper casting.
