An in-vehicle communication system includes a transmitter that transmits a differential signal, a receiver that receives the differential signal, and a communication cable that connects between the transmitter and the receiver and transmits the differential signal. The communication cable includes a twisted wire, a sheath covering the twisted wire, and a talc layer provided between the twisted wire and the sheath. The sheath includes a pair of ribs located across a straight line connecting a conductor center of a first coated wire and a conductor center of a second coated wire in a transverse section of the communication cable. The talc layer is provided along the surface of the twisted wire.

Cables having interlocking armor layers formed from improved aluminum alloys are disclosed. The aluminum alloys include magnesium and manganese and are capable of being formed without heat treatment upon formation of an aluminum alloy strip. The interlocking armor layers exhibit strength, ductility, and formability. Methods of making the interlocking armor layers are further disclosed.

A fire resistant radiating coaxial cable that employs a high-silica fiberglass yarn spacer is described. The yarn material has mass fraction of silica (SiO.sub.2) between 95.0% and 96.5%, a mass fraction of aluminum oxide (Al.sub.2O.sub.3) greater than 3%, and a mass fraction of calcium oxide (CaO) less than 0.5%. The yarn can be wound in a low-helix-angle helix around the center conductor such that less than half fills the annular space between it and the outer conductor. The cable is configured to maintain a relatively coaxial relation between a center conductor and an outer conductor under intense fire conditions.

Disclosed is an armored cable assembly including a core having a notched assembly tape about a plurality of conductors. A metal sheath surrounds the core.
