High-frequency high-voltage insulating lead-through terminal

The utility model belongs to the insulation field of a high-frequency high-voltage transformer, in particular to a high-frequency high-voltage insulating lead-through terminal, which comprises a sleeve, and a conductive column core sheathed in the sleeve, wherein the outer surface of the sleeve is provided with an insulating layer; two ends of the sleeve are sheathed with sealing sleeves; the sealing sleeves are fixed at two ends of the sleeve by screws; the sleeve adopts a Bakelite material; and the sealing sleeves are T-shaped copper rings. The insulating lead-through terminal can meet the insulating requirement of the high-voltage current of various specifications and can be adjusted conveniently; as long as the size of a middle hole and a conductive middle core can be changed, the requirement of different voltage insulation grades can be met; therefore, the high-frequency high-voltage insulating lead-through terminal is simple in manufacture, low in cost and applicable to batch production in factories.
