Abstract: An aspect of the present disclosure provides a shield for a terminal of a high-voltage electrical device including a first shield element having at least one axial opening and at least one lateral opening, and at least one second shield element, wherein the at least one second shield element is moveable between a first shield position and a second shield position for selectively opening and closing at least one of the at least one axial opening and the at least one first lateral opening. Further aspects provide a high-voltage electrical bushing comprising a shield according to the aspect above, and a transformer including said high-voltage electrical bushing. Yet a further aspect provides a method for installing a high-voltage bushing having a shield according to the aspect above.

Abstract: An electrical bushing having an anti-rotation mounting flange for preventing rotation of a body element of the electrical bushing is provided. The electrical bushing includes a mounting flange, at least one locking element and a body element having a circumferential protrusion. At least one first recess is formed in the circumferential protrusion, and the at least one locking element is configured to engage with the at least one first recess and with the mounting flange for restricting relative rotation of the body element relative to the mounting flange about a longitudinal axis R. A further aspect provides an electrical transformer including at least one electrical bushing according to the above. A yet further aspect provides a method for mounting the electrical bushing according to the above.
