inner conductor การใช้

• Inner conductors are sometimes silver-plated to smooth the surface and reduce losses due to skin effect.
• Coaxial railguns accelerate toroidal plasma armatures using a hollow outer conductor and a central, concentric, inner conductor.
• In this design the foil or mesh shield has a circular cross section and the inner conductor is exactly at its center.
• A high voltage direct current on the inner conductor powered repeaters ( two-way amplifiers placed at intervals along the cable ).
• The insulator surrounding the inner conductor may be solid plastic, a foam plastic, or air with spacers supporting the inner wire.
• Some coaxial lines use air ( or some other gas ) and have spacers to keep the inner conductor from touching the shield.
• Since there is essentially no current deeper in the inner conductor, there is no magnetic field beneath the surface of the inner conductor.
• Since there is essentially no current deeper in the inner conductor, there is no magnetic field beneath the surface of the inner conductor.
• The outer conductor is rippled like a bellows to permit flexibility and the inner conductor is held in position by a plastic spiral to approximate an air dielectric.
• A series of standard types of coaxial cable were specified for connectors that fit the inner conductor, dielectric, and jacket dimensions of the old RG-series cables.
• Wartime production of coax, and for a period afterwards, tended to use standard plumbing pipe sizes for the outer conductor and standard AWG sizes for the inner conductor.
• While 30 ? cable is highly desirable for its power handling capabilities, it has never been in commercial production because the large size of inner conductor makes it difficult to manufacture.
• The reason is that the socket in the middle is not deep enough for the pin ( actually, the solid inner conductor of the cable being connected ) to be inserted.
• The device works like a coaxial resonator, but it is much shorter because the helical inner conductor reduces the velocity of wave propagation ( Lancaster, 2006, p . 99 ).
• In " C ", however, there is a reduced magnetic field in the deeper sections of the inner conductor and the outer sections of the shield ( outer conductor ).
• The toroids are similar to spheromaks, but differ in that an inner conductor is used to accelerate the plasma and that confinement behavior results from interactions of the toroid with its surrounding atmosphere.
• According to Stephen Lampen of Belden Wire & Cable 75 ? was chosen as the nominal impedance rather than 77 ? because it corresponded to a standard AWG wire size for the inner conductor.
• Since the current in the inner conductor is balanced by the opposite current flowing on the inside of the outer conductor, there is no remaining magnetic field in the outer conductor itself where b.
• The outer ( shield ) conductor is connected to a quarter-wavelength conducting sleeve into which the cable is inserted, and the inner conductor protrudes vertically above the sleeve for a quarter-wavelength.
• A vampire tap clamps onto the cable, a hole is drilled through the outer shielding, and spike is forced to pierce and contact the inner conductor while other spikes bite into the outer braided shield.
