A wire harness includes an electric wire, a braided conductor covering the electric wire, a grommet having a tubular insertion portion through which the electric wire and the braided conductor are inserted, a water stop sheet sandwiched between an inner peripheral surface of the insertion portion and the braided conductor, and a fixture attached to the insertion portion so as to reduce a diameter of the insertion portion. The water stop sheet includes a base material layer having a plurality of pores communicating with each other in a thickness direction of the water stop sheet and a sealing compound layer laminated on the base material layer.

High-voltage insulators are disclosed that are capable of handling diverse requirements, such as providing high standoff voltages, high temperature cycling, and the ability to withstand flexural stress. One high-voltage insulator includes a first piece formed from a first material, a second piece formed from a second material, and an interface section where the first piece contacts with and forms a seal with the second piece. The interface includes a first groove located that accommodates a first gasket, sets of matching threads on the first and second pieces. The interface section further accommodates a second gasket. In this multi-piece high-voltage insulator, the first material can have a first set of flexural, heat resistance, and electrical standoff characteristics suitable for a first environment, and the second material can have a second set of flexural, heat resistance and electrical standoff characteristics suitable for a second environment.

A glass-metal feedthrough includes: an external conductor including steel, having a coefficient of expansion .sub.external, and having an opening formed therein; an internal conductor disposed in the opening, the internal conductor including steel and having a coefficient of expansion .sub.internal. The external conductor and the internal conductor are configured to not release nickel when in contact with a human or animal body or biological cells of a cell culture. A glass material surrounds the internal conductor within the opening and has a coefficient of expansion .sub.glass. The coefficient of expansion .sub.external of the external conductor and the coefficient of expansion .sub.internal of the internal conductor both are greater than the coefficient of expansion .sub.glass of the glass material.

Embodiments of the present disclosure relate to a sealing arrangement of a bushing for a power electrical device and a bushing comprising the sealing arrangement. The sealing arrangement includes a top cover; a central conductor going through the top cover; a guide element having a cylinder portion and a flange portion extended from a middle part of the cylinder portion, wherein the cylinder portion is arranged between the top cover and the central conductor, and the flange portion is connected onto the top cover; a static sealing structure provided between the guide element and the top cover; and a dynamic sealing structure provided between the guide element and the central conductor. With the new sealing structure design, it could provide a good sealing performance so that the bushing can be used in various environments.

Feedthrough device (50; 150), for forming a hermetic seal around signal conductors in a signal conductor group (60; 160) with a group width. The device comprises a slotted member (52; 152) and a base (62; 162). The base defines a through hole (65) that extends entirely through the 5 base along a feedthrough direction (X), and is adapted to accommodate the slotted member. The slotted member defines first and second surfaces (53, 54; 153, 154) on opposite sides associated with the feedthrough direction, and a side surface (55, 56; 155, 156) facing transverse to the feedthrough direction. The slotted member comprises a slot (58; 158), which extends along the feedthrough direction through the slotted member, and opens into the first and second surfaces and 10 into a longitudinal opening (59; 159) along the side surface. The slot extends transversely into the slotted member up to a slot depth at least equal to the signal conductor group width.
