Cooling and Insulation:

     This tube is intended to be used in an environment in which a high-grade transformer oil is used as the primary means of cooling and insulation.  
The oil should have a minimum dielectric strength of 45 kVp per ASTM D 877-49.  All ratings herein assume operation in well circulated oil at a temperature of 70 degrees C maximum.
