A communication cable includes a solid sheath on an outer periphery of a signal cable having a plurality of insulated wires and in which transmission characteristics hardly decrease due to a pressure in extrusion-molding a sheath. The signal cableincludes a plurality of insulated wireseach having a conductorand an insulation coatingcovering an outer periphery of the conductor, and a solid sheathcovering an outer periphery of the signal cable. A melt flow rate of a constituent material of the sheathmeasured at 200° and with a load of 2.16 kg is 0.25 g/10 min. or more.

Communication cable

A shielded communication cable. The shielded communication cable includes a pair of insulated wires twisted with each other containing a conductor and an insulation covering which covers the conductor and has the relative dielectric constant of 2.5 or lower, a braided shield which covers the pair of insulated wires, a film-shaped shield which contains a metal film and longitudinally laps the pair of the insulated wires over the braided shield and a jacket having an inner diameter of 3.5 mm or smaller which covers the film-shaped shield. The pair of insulated wires are twisted with each other with a twist pitch of 30 times of an outer diameter of each of the insulated wires or smaller, and the shielded communication cable has a characteristic impedance in range of 100±5Ω.

Shielded communication cable

Disclosed is a shielded communication cable containing a parallel electric cable containing a pair of insulated wires arranged parallel to each other without being twisted. The shielded communication cable exhibits excellent noise shieldability and hardly generates signal propagation time difference. The shielded communication cable contains a parallel electric cable containing a pair of insulated wires arranged parallel to each other. Each of the insulated wires contains a conductor and an insulation coating that covers the conductor. A braided shield containing elemental wires braided together and a film-shaped shield containing a metal film are arranged at an outer circumference of the parallel electric cable.

A communication cable includes a coating layer that contains a powdery magnetic material and that can suppress the occurrence of a powdery substance containing the magnetic material when processing the coating layer. The communication cable further includes a conductor, an insulating coating that covers an outer circumstance of the conductor, and a magnetic sheath layer that covers an outer side of the insulating coating, and the magnetic sheath layer contains the magnetic material and the magnetic material has a particle shape with an average particle diameter of not more than 50 &#x3bc;m and an aspect ratio of not greater than 4.

A shielded cable comprising two insulated wire covered with first and second metal clad resin tapes each of which has a laminated metal layer and a resin layer. The first metal clad resin tape covers the circumference of the two insulated wires by open-wrapping and the second metal clad resin tape is spirally wrapped around the circumference of the first metal clad resin tape. The first and second metal clad resin tapes are disposed while the metal layers face each other and, in the portion where the second metal clad resin tape is overlapped by wrapping, the metal layer of the overlapped one second metal clad resin tape and the metal layer of the other second metal clad resin tape are in contact with the first metal clad resin tape. The shielded cable can prevent sharp signal attenuation in a high frequency region and is easy to bend and flexible.
