Abstract

The utility model relates to the technical field of high-voltage wire shielding press rings, and discloses a high-voltage wire shielding tensile shielding press ring structure, which comprises a high-voltage main wire and a lantern ring component arranged on the high-voltage main wire, wherein a fixing component and a tensile component are arranged on the lantern ring component, and a connecting component is arranged between the tensile component and the high-voltage main wire, wherein the tensile component is designed to enable a joint of a shielding layer to be continuously opposite in force when the shielding layer is pulled, so that the shielding effect of the shielding layer in the high-voltage wire is lost due to the fact that the shielding layer is pulled out of the shielding layer when the high-voltage wire is pulled by external force is avoided, and meanwhile, the lantern ring component and the connecting component are designed to enable the shielding layer to be directly connected with the lantern ring component through the connecting component when a new shielding press ring is replaced, so that subsequent maintenance and replacement of the lantern ring are facilitated.
