MANUFACTURE OF SOLID-INSULATION COVERED POLE OF SWITCH Russian patent published in 2008 - IPC H01H33/66 

Abstract RU 2318265 C2

FIELD: electrical engineering.

SUBSTANCE: proposed method for manufacturing solid insulation covered pole 1 with operating hole involving separate production of switch 2 with case 3 that has operating side 6 pierced by operating rod 9 and stable-shape enclosure 7 made of insulating material and provided with connecting part 6 includes fixation of switch 2 in enclosure 7 so that its case 3, except for operating side 8, and enclosure 7 provided with connecting part 6 confine intermediate space open in direction of operating hole; then intermediate space is filled with compensating fluid mass 10 followed by solidifying the latter. Proposed solid insulation covered pole 1 for current-interrupting switch has priming duct.

EFFECT: enhanced economic efficiency with respect to manufacturing cost.
