Multiple phase spacer with insulator as central element - has central insulator and two outer insulators connected by suitable fittings

摘要

The central insulator does not have any ribs but the two outer insulators have ribs. The central insulator (2) and outer insulators (3) are provided with clamps (9-11). Each first clamp (10) of an outer insulators (3) is connected by a fitting (5) to a clamp (11) of the central insulator (2), and each other clamp (9) of the outer insulator (3) has a fitting (7) with a flat connecting piece (15). The insulators are long rods and the ribs where fitted are flat discs.
