摘要:
The invention is directed to an insulator (1) for a gas insulated device. The insulator comprises an injection molded insulator disc (2) and a conductor (3). The insulator disc (2) is made by injection molding of a first material. The insulator disc (2) comprises a center opening (4) encompassed by an inner bead (5) inside which the conductor (3) is arranged. A gap (18) arranged between the inner bead (5) and the conductor (3) is at least partially filled with a second material to form a transition means (19) between the insulator disc (2) and the conductor (3).

A conductor handling tool has a plate-shaped tool body (10). The tool body (10) comprises a conductor receiving opening (20) for receiving a conductor portion therein and for holding the conductor portion received therein. Further, an edge of the plate-shaped tool body is shaped convex as a tapered blade edge (12) extending essentially within a y-z-plane. The tapered blade edge (12) is directed away from the conductor receiving opening (20) and is forming an outer circumferential portion of the tool body (10) for splitting a portion of insulating material during winding of the insulating material.

摘要:
A method of pre-treating an electrically conductive substrate (12) for bonding a non-metallic material (14) thereon is provided. The method includes: (a) placing the substrate (12) in a laser range of a laser source (16); and (b) irradiating a surface (18) of the substrate (12) with a laser light (24) from the laser source (16), thereby forming a micro-structure (20) on the substrate surface (18). The micro-structure (20) has at least one of: a) an I/Ra ratio of at least 0.2 μm -1 , I being the surface index, Ra being the average roughness; or b) an I/Rz ratio of at least 0.03 μm -1 , I being the surface index, Rz being the average peak-to-valley distance. An electrically conductive substrate (12), a metal insert (12, 603) for use with a solid insulation component (704, 706, 712, 714), an insulator-conductor assembly (26), and a gas-insulated switchgear station (700) are also provided as well as use of an insulator-conductor assembly (26, 600) in an electrical power system (700).

A composite frame (100) for an electrical machine includes an outer frame member (102) comprising a composite material including fibers having an aspect ratio of at least 1500. The outer frame member forms a central aperture (106) for holding an electrical machine (108). The outer frame member forms an outermost layer of the portion of the composite frame for surrounding the electrical machine and extending axially beyond laminations of the electrical machine. An attachment mechanism (104) is formed on at least one end of the frame member for attaching the frame member to a mechanical system.
