The Jeffery-Dewitt Insulator Company of Huntington, W. Va., have issued a new high tension disc insulator catalogue, No. 2. In addition to illustrations and details regarding the various insulators manufactured, there are illustrations of typical installations and high tension tests, with data regarding the tests, both mechanical and electrical, which are made on all insulators. Tests are made at both 60 cycles and with a 200,000 cycle oscillator. The new plant of the Jeffery-Dewitt Co. at Kenova has only recently been completed and is one of the most upto-date in the country.
