COAXIAL HIGH-FREQUENCY CABLE
Document Type and Number:
Japanese Patent JPH0620534
Kind Code:
A
Abstract:
PURPOSE: To provide a coaxial high frequency cable whose functions do not deteriorate even under the action of flames by interposing a helical spacer made of a glass material or ceramics between the inner and outer conductors of the coaxial high frequency cable. CONSTITUTION: A helical spacer 2 made of a glass material or ceramics is placed halfway between the inner conductor 1 and outer conductor of a coaxial high frequency cable. The incombustible helical spacer of glass material or ceramics or the like comprises a twisted or knitted single strand or single thread, its surface being surrounded or covered with a braiding 3. The helical spacers 2 deviate from one another by an angle of 90 degrees or more and have longitudinal slits formed from an end to the center, and even if the temperature around the cable is elevated at a fire, its functions as a cable do not deteriorate.
