Dry Electrochemical Condensers

Operating characteristics of compact, dry, electrochemical, high-voltage filter condensers, comprising a dielectric plated sheet electrode contacting with a gummed spacer rolled with an untreated electrode sheet, show that such condensers are in all respects suitable for power-pack filter service and effect large reduction in costs. Commercial condensers of this type have working voltages up to 700 volts d-c. The leakage current, which determines the merit of an electrochemical condenser, is extremely small in the case of the gum condenser and affords a very long operating life. Gum condensers are operable in the extreme temperature range from -30 deg. F through +250 deg. F.
