Electricity insulating disc for supporting a linear conductor and electric system comprising such a disc

摘要

The disk (1) has a central hole (4) for a linear conductor and two opposite main faces (2, 3). The opposite faces are flat, except for a central recess (5) that extends around the hole, and a peripheral recess (6) that extends in an edge portion of the disk. An inner collar (8) is arranged between the hole and the central recess, and an outer collar (9) is arranged on the peripheral recess. The central recess has a depth in the range of 10 to 20 percentages of thickness of the disk. An independent claim is also included for an electrical assembly comprising a linear conductor and an insulator disk.
