An insulator includes an insulation tube, an insulation foam body disposed in the insulation tube, and a curable adhesive disposed between the insulation foam body and an inner wall of the insulation tube. The curable adhesive after being cured is softer than both the insulation foam body and the insulation tube.

Disclosed are an insulated pipe and an insulated bushing. The insulated bushing (1000) includes: an insulator (110) including an intermediate shed member (112), and a lower flange (114) arranged on a lower end of the shed member; a head member (120) connected to an upper end of the insulator, wherein the head member includes an oil conservator (121) connected to the upper end of the insulator and a connecting terminal (122) connected to the oil conservator; and an insulated pipe (100) connected to the lower flange, wherein the insulated pipe includes a upper transformer pipe (101) and a lower oil-immersed pipe (102), and the transformer pipe includes an inner pipe (103), and a conductive layer arranged outside the inner pipe and configured to be grounded. The insulated pipe and the insulated bushing solve the problems of connection and sealing, and save material cost greatly.

An insulator for high-voltage applications has 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. The retainer has a rotationally symmetrical connection region. The insulator further has at the upper end of the hollow tube, a radially circumferential joining region which has no silicone shielding. 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.

This invention relates to a supporting structure for contacts of high-voltage disconnectors, characterized in that it comprises at least one vertical central composite insulator that is stayed by means of at least two inclined insulators, each of which is coupled at a first end to said at least one central composite insulator and at the second opposite end to a base body for said at least one vertical central composite insulator.

A composite insulator (1) for overhead power lines comprises a rigid core extending axially between two attachment fittings (6) and having placed thereon a shell having sheds (5, 5) made of electrically insulating synthetic material. It includes a detector device for detecting surface leakage currents, which device includes an electrically conductive metal annular ring (7) surrounding the shell between an end shed (5) adjacent to one of the two fittings (6) and another shed (5) adjacent to the end shed (5) that extends radially over the ring (7). The ring (7) is connected by a conductive wire (8) passing through the end shed (5) to be connected to an electronic unit (9) of the detector device.

A jacket assembly for a separable connector includes multiple pieces joined by an overlapping or interference fit. The multiple pieces include a body segment between a cable entrance segment and a bushing interface segment. The cable entrance segment includes a bore that extends axially through the cable entrance segment and is sized to receive an insulated power cable. The bushing interface segment includes a lug portion with another bore that is sized to receive a portion of an insulative inner housing and a portion of a conductive insert for accepting a compression lug. The bushing may also be configured to receive another portion of the insulative inner housing and another portion of a conductive insert for accepting a probe or bushing insert from another device. The body segment includes still another bore extending axially from a first end of the body segment to a second end of the body segment.
