Definitions
- the invention relates to a concentric three-wire cable, in particular for ultrasound measurements, with an inner conductor and outer conductors made of braided strand, which are spaced from one another and from the inner conductor by insulating material.
- the outer conductors each consist of several layers and that their direct current resistance is several times smaller than that of the inner conductor.
- the new cable has an extremely high coupling loss.
- the resistance ratio between outer conductors and inner conductors can advantageously be 1: 5 or more and thus considerably exceeds the values of conventional measuring cables, which have a lower coupling loss.
- the outer conductor adjacent to the inner conductor should comprise three or more layers of braided silver-plated copper braid, which are offset from one another to achieve a high degree of coverage. Despite the desired high degree of coverage, good flexibility is achieved.
- the insulating material can consist of polytetrafluoroethylene, the thickness between the inner conductor and the first outer conductor being dependent on the required characteristic impedance of the cable.
- a jacket with approximately the same thickness as the insulating material is recommended as external protection. It is suitably made of polyurethane, which can be colored to make the cable more noticeable or to mark it.
- the construction of the new triax cable with extremely high coupling attenuation with a small diameter ( v 6 mm) and good flexibility as well as a robust design is described in the direction from the inside out.
- the cable consists of an inner conductor 1 made of copper strands 7 x 0.18 silver-plated, ie seven copper wires with a diameter of 0.18 mm, which are silver-plated and twisted together.
- the DC resistance is 100 m ⁇ / m.
- the subsequent dielectric 2 consists of highly insulating material, namely polytetrafluoroethylene, which is extruded onto the inner conductor 1.
- the outer diameter of 1.7 mm corresponds to an insulating material thickness of approximately 0.6 mm. This gives a characteristic impedance of approximately 50 ohms.
- the inner shield 3 comprises three braided shields, which consist of silver-plated copper braid.
- the copper strand is spun in several, for example 16 strands of several, for example 5 or 6 conductors with a diameter of 0.1 mm to form an acute-angled braid.
- the shield 3 has an outer diameter of 3.0 mm and a direct current resistance of 12 m ⁇ / m.
- the inner shield 3 is followed by a second insulation 4. It is also made of extruded polytetrafluoroethylene and has an outer diameter of 3.8 mm.
- the outer shield 5 of the triax cable consists of two braided shields made of silver-plated steel copper wire, which can also achieve a good degree of coverage. 24 beats of 5 or 6 individual conductors with a diameter of 0.13 mm are spun at an acute angle. This results in an outer diameter of 5 mm and a direct current resistance of 17 m ⁇ / m.
- the outer jacket 6 is made of polyurethane. It gives the outside diameter of 6 mm.
- the decisive advantage of the invention lies in the extremely high coupling loss of> 140 dB of the cable. This is achieved through the use of multi-layered umbrellas, which enable a high degree of coverage with low longitudinal resistance and great flexibility.
- the shielding effect relates not only to electrical fields, but also to magnetic fields due to the use of steel copper in the outer shield due to the magnetostatic effect.
- the cable can therefore be used not only for ultrasonic measurements but also in data technology to reduce the sensitivity to interference.
