Abstract

620,941. Insulators. REYROLLE & CO., Ltd., A., and AMER, D. F. Feb. 3, 1947, No. 3202. [Class 36] [Also in Group XXXVII] Each unit of a multi-break circuit-breaker is housed in a shedded insulator B<SP>1</SP>. The external resistance path of the shed B' of the insulator B<SP>1</SP> exceeds that of part B<SP>8</SP> of the insulator so that the greater part of the resistance is perpendicular to the axis of the insulator. The insulator may have a semi-conducting glaze on its surface to form a resistance across the switch contacts.
