Fluid insulator from London

Fluid Insulators.

A type of insulator hitherto little known is coming into use. A recess in the porcelain body of the insulator is filled with an insulating fluid which neither freezes nor evaporates, and will not support the slightest film or dust. Other recommendations claimed for it are that it does not creep like paraffine or other mineral oils, and lasts three or four years, even in the hottest and driest climate. A clean and highly insulating fluid surface is thus interposed between the line and the earth, and the insulators are found to be especially efficient in rainy weather. The insulation fluid is prepared in London under a secret process. — New York Telegram.
