Beschreibung
Zusammenfassung:	The present invention relates to a dry-type plug-in bushing, a manufacturing method of same, and a high-voltage installation, more specifically, to a plug-in high-voltage bushing for connecting an external electrical conductor to a high-voltage installation filled with an insulating body, and to a high-voltage installation comprising said bushing. The dry-type plug-in bushing comprises: a conducting body; a cast-type resin insulating body surrounding the conducting body; an electric field-control electrode made of a semi-conducting synthetic resin material, coupled to an upper end of a lower support fitting; the lower support fitting connected to the outer circumference of a lower part of the cast-type resin insulating body; and injected insulating body produced by an insert injection including the outer circumference of the cast-type resin insulating body and electric field-control electrode, having formed thereon a plurality of fins; and a stress cone connected to a lower end of the cast-type resin insulating body.
