Abstract

Improvements introduced in the manufacture of insulated electrical cables having an impregnated fibrous material dielectric, according to which the impregnant within the fibrous material and in the interstices between the coils and layers thereof is a normally plastic solid consisting of micro-petroleum wax crystalline that has a melting point of about 88ºC. and needle penetration values of approximately 5 to 25ºC. and approximately 35 to 70ºC.
