SYSTEM OF TWO OR SEVERAL INSULATING COMPONENTS FOR MANIFACTURING OF MEDIUM VOLTAGE CABLE FITTINGS Russian patent published in 2010 - IPC H02G15/115 H01R4/70 

FIELD: electricity.

SUBSTANCE: system (1) of two or several insulating components for manufacturing of medium voltage cable fittings with automatically fixed electrically insulating lock, for instance for installation of cable connections in it, includes at least the first insulating component (2) with linear roll-like gripped element (3) arranged in its coupling surface (4) at the end side, which enters, as in lock with latch, into according gripping element (6) that matches it in shape at the end side of coupling surface (4) in the second insulating component (5). At least one insulating component (2 or 5) surrounds active current-conducting connection elements, and linear closed roll-shaped gripped element (3), forming lock, and also gripping element (6) that matches it in shape in both connected insulating components (2, 5), by shape of their cross section are arranged as concave-convex rounded coupling wit area (7) of head in gripped element (3) and area (7) of hole in gripping element (6) and with area of journal (8), separated from neighbouring areas by points of curvature bend, in each element, and also with area (9) of collar that borders area (8) of journal, in each element.

EFFECT: invention provides for creation of easily mounted system that prevents electric breakdown.
