The utility model discloses an isolated wire for a high-voltage current transformer, and the wire is simple in structure, enables high-voltage power to be effectively isolated from a current transformer, and avoids a high-voltage punch-through phenomenon. Two ends of the isolation wire are electrically connected with a common high-voltage wire. The whole of the isolation wire passes through the central ring of the current transformer. The isolation wire comprises a conductor layer, an internal semiconductor shielding layer, an insulating layer, an external semiconductor shielding layer, a conductor shielding layer, an outer sheath, a grounding wire, and a high-voltage heat-shrinkable tubing. The conductor layer serves as an axis. The internal semiconductor shielding layer, the insulating layer, the external semiconductor shielding layer, the conductor shielding layer and the outer sheath are sequentially disposed at the exterior of the conductor layer from the inside to the outside in a concentric mode.
