- In Germany November 2!, 1830 2 Claim. (Cl. 17H) This invention relates to electric cables and more particularly to cables adapted for the transmission of high frequency currents.
The object of this invention is a special em- .bodiment' and form of construction of a high frequency cable. According to the present improvement the materialused for insulating the inner conductor from the outer conductor consists oi quartz wool or some similar elastic substance. The use of quartz wool is particularly recommendable whenever the inner and the outer conductors are flexible in nature inasmuch as the radio irequency cable can then be flexed u a whole just like a standard cable and can thus'be easily wound or rolled up. Quart: wool furthermore constitutes a good insulator whose phase (angle) diflerence is of a particular order oi magnitude iortheirequencieshereeominginto consideration. The inner conductor may most suitably consist of stranded wire, while the outer inlay consist, if desired. oi. a wire gauze or metal One embodiment of the invention is illustrated in the attached drawing where T the" inner conductor, A the outer, and G the quartz wool.
I claim:
LInasystemcarrying radioirequencycurrents, a flexible cable transmitting said currents, said cable comprising concentric inner and outer conductors. said conductors being insulated from each other by quartz wool. v I
2. Ina system carrying radio frequency currents, a cable comprising inner and outer flexible conductors.- said outer conductor being composed of wire gauze, the said inner conductor being composed of stranded wire, both 01' said conductors being insulated from each other by quartz wool.
