An electrical insulator disk has central recesses and peripheral recesses to enable the disk to be mounted floatingly relative to flanges between which the disk is held and to a linear conductor that extends through the disk.

Insulator disk for supporting a linear conductor, and an electrical assembly including such a disk

An assembly for a grounding disconnector, a grounding disconnector including the assembly and a method of manufacturing a grounding disconnector are described. The assembly includes a stationary grounding contact (), a phase contact () suitable for being connected electrically to a busbar (), moving connection means () suitable for putting the stationary grounding contact () and the phase contact () into electrical contact with each other, the stationary grounding contact (), the phase contact () and the moving connection means () being mounted on a mounting plate ().

Grounding disconnector and a method of manufacturing such a grounding disconnector

Supports for high or medium voltage electrical conductors () at potentials different from the potential of an enclosure () are supported by disc-shaped parts () made from thermoplastic polyester, for example terephthalate polyethylene. The discs (and) provide good insulation without largely disturbing the electrical field around the conductors due to their fairly low dielectric constant. They are also compatible with use under SFgas.
