1. An insulator for high-voltage applications, the insulator comprising:
a rotationally symmetrical hollow tube made from fiberglass-reinforced epoxy resin;
a silicone shielding attached to a periphery of the hollow tube;
a base flange at a lower end of the hollow tube;
a retainer, which is configured to retain an electrical operator, at an upper end of the hollow tube; and
a plug, which is arranged inside the hollow tube and closes the front side of the upper end of the hollow tube and seals the hollow tube from the outside,
wherein the retainer has a rotationally symmetrical connection region,
wherein the insulator further comprises at the upper end of the hollow tube, a radially circumferential joining region which has no silicone shielding, and
wherein the retainer is connectable to the insulator in such a way that the connection region of the retainer surrounds the joining region of the insulator in a form-fitting fashion.
