Abstract

894,308. Oil-blast switches. ELEKTROTECHNICKE ZAVODY J. FUCIKA, N.P. BRONO. Dec. 15, 1959 [Dec. 15, 1958], No. 42577/59. Class 38 (5). An interrupting chamber for an oil-blast circuit-breaker is formed from cast synthetic resin with an insert 1 of high mechanical impact strength. The resin may be an epoxide resin with a silica filler. The insert is perforated and may be of sheet metal.
