An insulating support (20) for insulating an electrical conductor contained in aligned casing portions (34, 35), is held in a housing (39) defined by the flanges (36, 37) for joining the casing portions (34, 35) together, the flanges presenting contact faces (38) around the periphery (24) of the sup
An insulating support (20) for insulating an electrical conductor contained in aligned casing portions (34, 35), is held in a housing (39) defined by the flanges (36, 37) for joining the casing portions (34, 35) together, the flanges presenting contact faces (38) around the periphery (24) of the support (20). A single sealing gasket (41) is sufficient to prevent the atmosphere in the casing leaking to the outside, and that simplifies assembly of the electrical equipment, while at the same time protecting the support (20) from the outside. For application to medium- and high-voltage electrical equipment.

1. Electrical equipment comprising two portions of a casing for at least one electrical conductor, an insulating support for the conductor through which the conductor passes and which bears against the casing, wherein flanges extend from each of the portions of the casing and the portions of the cas
1. Electrical equipment comprising two portions of a casing for at least one electrical conductor, an insulating support for the conductor through which the conductor passes and which bears against the casing, wherein flanges extend from each of the portions of the casing and the portions of the casing being joined by the flanges and the insulating support having a peripheral portion that is housed between the flanges; the flanges having faces that are in contact, and a sealing gasket being compressed between said faces and surrounding the peripheral portion; the flanges have parallel plane faces between which the peripheral portion is housed and circular faces which are cylindrical-in-shape extending from each other and surrounding the peripheral portion, wherein the support comprises a collar on an outer edge, said collar projecting in a radially outward direction and a collar on an essentially planar face, the flanges define a housing that receives the peripheral portion is housed in a housing of the flanges with a clearance, except at the collars, which respectively bear against the circular face of one of the flanges and the parallel planar face of one of the flanges. 2. Electrical equipment according to claim 1, wherein at least one of the collar on the outer edge and the collar on the essentially planar face has at least one gas passing channel cut therein. 3. Electrical equipment according to claim 1, wherein the support is of thickness that is essentially uniform in a main portion extending from the peripheral portion towards a central region of the support, the peripheral portion having a thickness that is not less than that of the main portion. 4. Electrical equipment according to claim 3, wherein the support is a disk of thickness that is essentially constant. 5. Electrical equipment according to claim 4, wherein the electrical equipment is three-phase electrical equipment and includes three electrical conductors extending in parallel. 6. Electrical equipment according to claim 3, further comprising means for fastening the support to one of the casing portions. 7. Electrical equipment according to claim 6, wherein the fastener means comprise screws engaged through the peripheral portion and in tapped holes established beyond the plane face of the flange of said one of the casing portions. 8. Electrical equipment according to claim 7, wherein the support includes metal bushings in which the screws are engaged, with screw heads pressing against the bushing. 9. Electrical equipment according to claim 1, further comprising another sealing gasket, compressed between the peripheral portion and one of the plane faces of the flanges. 10. Electrical equipment according to claim 1, wherein the conductor comprises a coupling that is secured to the support, a first linear conductor extending in one of the casing portions and joined to the coupling in removable manner by being engaged in a concave side of a corona shield belonging to the coupling and including a spring situated in the concave side of the corona shield, and a second linear conductor extending in the other casing portion and joined to the coupling by being fastened thereto.
