Abstract

813,533. Insulators. ETABLISSEMENTS MERLIN & GERIN. July 25, 1956 [July 27, 1955], No. 22967/56. Class 36. [Also in Group XXXVII] An elliptical and preferably ethoxylin resin insulator has fixing studs 37, 38 embedded in the resin, as are locating pins 35, 36 and a fixing stud 34 for equipment such as a circuit-breaker arc-shoot assembly. Electrodes 39, 40 are also embedded in the insulators to equalize the positive and negative impulse flash over values.
