High Voltage Heated Insulator.


A patent has been granted to Mr. A. Sinding Larsen, of Frederiksvaern, Norway, on a new form of heated high-voltage insulator. The insulators for this purpose are generally made out of insulating material and formed with hoods or bell-shaped flanges, the purpose of which is to prevent moisture from forming a continuous conducting film or connection between the metallic conductor and the post or bracket carrying the insulator. It is known, however, that whatever form such insulator is given it is not possible to prevent the condensation of moisture unless special means are employed; and the object is to provide means for preventing such condensation on a part of the insulator to break the conducting sur
