Abstract
Abstract Several types of seals for current-carrying leads of electrolyzers are disclosed. A funnel-shaped member is attached to the housing of the electrolyzer in such a manner that it surrounds the lead as it emerges from the electrolyzer. The annular space between the lead and the funnel-shaped member is sealed with a thermally and chemically resistant packing which is confined therein. Suitable packing materials include slag cotton, asbestos cord and asbestos fluff and fibrous glass.
