摘要： An electric cable for conveying signals, the cable having a diameter of less than 2 mm and comprising at least one conductor in an insulating sheath, the sheath having a dielectric constant ε of less than 1.7. To achieve this, the sheath is made of PTFE and it includes at least one continuous cell. Fabrication is preferably by performing the following operations: compressing a lubricant-impregnated PTFE powder in a converging chamber arranged in an extrusion die and around a guide for guiding said at least one conductor, the impregnated PTFE powder thus being thrust towards an extrusion orifice to form an extrudate; causing said extrudate to pass from said orifice along an extrusion passage inside the die, in which it is shaped around the conductor(s), and of inside section that corresponds to the outline desired for the sheath; passing said extrudate around at least one solid bar presenting, at least over a distance within the extrusion passage, the same section as said cell and thereby preventing the extrudate from occupying the section that is to be occupied by said cell, the cell(s) being formed from the downstream end surface(s) of the bar(s) and extending downstream therefrom; extracting the lubricant by evaporation; and sintering the resulting assembly.

摘要： Carbon formation on voltage breakdown and sparking, and consequent carbon deposits on insulators and other surfaces, is suppressed in dielectric gases of halogenated alkanes by adding SF.sub.6 and/or CO.sub.2 to the halogenated alkane to form a gaseous dielectric mixture. Moreover, certain of the gaseous dielectric mixtures evidence unexpectedly high dielectric breakdown voltages. The gaseous dielectric mixtures are useful in high voltage coaxial lines, in transformers, in minisubstations, and the like.

摘要： Materials are described which are useful as gaseous dielectric insulators in electrical devices. These materials are a group of sulfur compounds which have two fluorine atoms and at least one perfluoroalkylimino group attached to the sulfur atom. It has been discovered that the substitution of a perfluoroalkylimino group for an oxygen atom attached to a sulfur atom increases the dielectric breakdown voltage of the molecule. These gaseous materials can be used both in substantially pure form or mixed with inert gaseous material. They exhibit high breakdown voltages and in addition do not yield undesirable reaction products when exposed to dielectric breakdown.
