Abstract

Insulating-liquid for electrical apparatus consists of vegetable oil with 20 per cent or more of trichlorbenzene. Other halogens may be substituted for the chlorine and other halogenated benzene compounds, such as benzene-trifluoride or chlorinated benzo-trifluoride, may be employed. The Specification as open to inspection under Sect. 91 also describes the use of similar compositions containing mineral oil. This subject-matter is disclaimed in the Specification as accepted.
