Abstract (en)
[origin: US4562321A] The operating rod 24 of a high-voltage puffer circuit-breaker is guided inside the support insulator 12 by insulator guides 40 mounted in the areas where the superimposed porcelain sections 14, 16 of the support insulator 12 join. A sealing O-ring 44 is inserted between the porcelain sections 14, 16 and circumferentially surrounds the edge 42 of the insulator guide 40 to center the latter.
